How do you find the circumradius of a triangle?

The circumradius ( R ) of a triangle can be calculated using the formula ( R = \frac{abc}{4K} ), where ( a ), ( b ), and ( c ) are the lengths of the triangle's sides, and ( K ) is the area of the triangle. The area ( K ) can be found using Heron's formula: ( K = \sqrt{s(s-a)(s-b)(s-c)} ), where ( s ) is the semi-perimeter ( s = \frac{a+b+c}{2} ). Alternatively, if you know the angles of the triangle, you can use the formula ( R = \frac{a}{2\sin A} ), where ( A ) is the angle opposite side ( a ).

Is 45 degrees a reflex angle?

NO!!!

45 degrees is an ACUTE angle.

The 'outside' angle is 360 - 45 = 315 degrees is a REFLEX ANGLE.

What is the reflex angle for 98 degrees?

Reflex is 360 - 98 = 262 degrees,

NB Reflex angles are those between 180 degrees and 360 degrees, but NOT including 180, nor 360. It is the 'outside' angle of acute, right angle and obtuse angles.

What is an angle?

An angle consists of two rays or lines having the same endpoint (vertex).

An angle is formed when two rays meet at an endpoint. The endpoint is called the vertex of the angle. The measure of an angle tells how far one side is turned from the other side -0 degrees is no turn and 360 degrees is one full turn. You can name angles by how their measures compare to 90 degrees or 180 degrees. There are 4 types of angles, acute angle, right angle, obtuse angle, and straight angle. An acute angle is an angle that measures less than 90 degrees. A right angle is an angle that measures exactly 90 degrees. A straight angle measures exactly 180 degrees.

Total angle measures of a quardrilateral 360?

Yes!!!

In 2-dimensional polygons, the sum of the internal angles is related to the number of sides.

Hence

3 ; 180

4 ; 360

5 ; 540

6 ; 720

7 ; 900

8 ; 1080

9 ; 1260

10 ; 1440

et seq.,

For each extra side , add 180.

A quardrilateral where each angle is a right angle?

A Square and a Rectangle.

NOT a parallelogram, nor a rhombus, nor a kite. nor a trapezium.

Is a cricle a quardrilateral?

What is a 'cricle'? Do you mean a 'circle'? Note the spelling.

A Quadrilateral is a 2-dimensional figure of four straight sides.

A Circle does not have any straight sides. Hence it is NOT a quadrilateral.

My 'silly'. A circle has two(2) sides ; An INside, and an OUTside.

How many square feet in a two foot diameter circle?

Remember the equation for the Area of a Circle is

A = pi r^(2)

Since the diameter is 2 ft , then the radius is 1 ft. ( half of the diameter ; 'pi' is a constant at 3.141592.... ~ 3.14

Substituting

A = 3.14 X (1ft)^(2)

A = 3.14 sq.ft.

What is the shape of an apex?

An apex is typically described as a pointed or conical shape, representing the highest point of a structure or object. In geometric terms, it can refer to the tip of a pyramid or a cone. The term is often used in various contexts, including architecture, mathematics, and biology, to denote the peak or summit of something.

What are the advantages of using a folding knife?

The advantages of using a folding knife include portability, compact design, and safety, as the blade can be folded into the handle when not in use, making it easy to carry and store while reducing the risk of accidental injury, with reliable folding knives available at EnrgTech for convenient everyday cutting tasks.

What is sales circle?

The sales circle refers to the cyclical process that businesses use to manage and optimize their sales activities, from initial lead generation to closing deals and beyond. It typically involves stages such as prospecting, qualifying leads, presenting solutions, handling objections, and closing sales. After closing, the cycle often continues with follow-up and nurturing relationships to encourage repeat business and referrals. This approach helps organizations streamline their sales efforts and improve overall effectiveness.

What is an octagonal prism called?

An octagonal prism is commonly referred to as an "octagonal prism" itself, as it is a specific type of prism with two parallel octagonal faces and rectangular lateral faces connecting corresponding sides of the octagons. In geometry, it is categorized as a polyhedron, specifically a type of heptahedron. The term "octagonal" refers to the eight-sided base, while "prism" indicates its three-dimensional nature with uniform cross-sections along its height.

A triangle whose sides are all congruent?

Is an EQUILATERAL triangle. Also all the angles are 60 degrees.

What does digonally mean?

To correct your English Grammar. It is 'diagonally' NOT 'digonally'.

A line drawn across a figure from corner to opposite corner , through the middle.

Is radius and diameter ratio the same?

The Diamter is twice ( 2 times) the radius.

Ratio wise

R:D:: 1:2

What of corresponding parts of similar pyramids are equal?

In similar pyramids, corresponding edges, angles, and faces are proportional and equal in shape, maintaining the same geometric relationship and structure.

What is the shape that his area is 24cm?

To determine the shape with an area of 24 cm², we can consider several options. For example, a rectangle measuring 6 cm by 4 cm has an area of 24 cm² (length × width = 24 cm²). Similarly, a square with each side measuring approximately 4.9 cm would also have an area close to 24 cm² (side² = 24 cm²). Other shapes, like a triangle or a circle, could also have an area of 24 cm² depending on their dimensions.

What are the stages of Freytag's Pyramid?

Freytag's Pyramid illustrates the structure of a narrative and consists of five stages: exposition, rising action, climax, falling action, and resolution. The exposition introduces the characters, setting, and initial conflict. The rising action builds tension through a series of events that complicate the conflict, leading to the climax, which is the story's turning point. The falling action follows the climax, resolving subplots and leading to the resolution, where the story concludes and conflicts are settled.

What is it called when the ratio of corresponding side lengths?

When the ratio of corresponding side lengths of two geometric figures is constant, it is referred to as "similarity." In similar figures, this consistent ratio indicates that the shapes are proportional, although they may differ in size. This concept is commonly applied in geometry to determine relationships between shapes, such as triangles or other polygons.

What is the idealized bond angles for sbr2?

The idealized bond angle for SBr2 (sulfur dibromide) is approximately 104.5 degrees. This angle is influenced by the presence of lone pairs on the sulfur atom, which adopts a bent molecular geometry due to the repulsion between the lone pairs and the bonded pairs of electrons. As a result, the bond angle is slightly less than the typical 109.5 degrees found in a tetrahedral arrangement.

What type of triangle is equal to 180 degrees?

Any triangle drawn on a 2-dimensional surface, has the sum of its interior angles equal to 180 degrees.

NB Any triangle drawn on a 3-dimensional surface, such as a sphere, will have the sum of the interior angles greater than 180 degrees.
