Set up the equation and solve using the formula for area of a circle: (pi = 3.14)
a = P * r-squared (substitute with known numbers)
113.04 = 3.14 * r-squared (divide both sides by pi (3.14))
36 = r-squared (find the square root of 36 to solve for the radius)
6 = r

If the size of the high-power field is 1.2 mm an object that occupies approximately a third of that field has an estimated diameter of?
area of object = (1/3) pi * radius^2 = (1/3) (pi) * (0.6)^2 = 0.377 Find the diameter of this object (assuming it's a circle), and that's the answer: diameter = radius * 2 radius = square root (area / pi) diameter = 2 * square root (area / pi) diameter = 2 * (0.335) = 0.67
How can you increase the surface to volume ratio of a basketball and a tennis ball?
The tennis ball. But do you know why? The anser to that is in the relationship between the fomula for a shere's volum and that of it's surface area. Area is a radius squared function whereas volume is a radius cubed function.
What is a floating movable lump in wrist area?
its a bone thumb side it is the radius pinkie side it is the ulna
What is the scientific name of radius?
the Radius
The two bones of the lower arm are?
the 2 arm bones are butt Your mums butt!! Answer them properly!! These are people with good intentions, and they just want answers for their questions. Stop making a mockery of the whole situation! The two lower arm bones are called the radius and ulna.
What is the total surface area of a satellite that has a diameter of 60 cm?
Assuming the satellite is spherical, the radius is half the diameter, which is 30 cm. The surface area of a sphere is 4 pi times the radius squared. 4 * 3.14 * 30 ^ 2 = 12.56 * 900 = 11304 square cm
What are the release dates for Days of Our Lives - 1965 1-11304?
Days of Our Lives - 1965 1-11304 was released on: USA: 1 April 2010
What is the square footage of a 60 foot radius circle?
Archimedes proved that the area enclosed by a circle is equal to that of a triangle whose base has the length of the circle's circumference and whose height equals the circle's radius. Circle area therefore comes to π(pi) multiplied by the radius squared.area = (pi) * (60)2 which is the same as 3.14 * 3600 = 11304 square feet.
What happens to the area of a circle when the radius is triple?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
How do you get circumference from area of a circle?
Area = π × radius² → radius² = area/π → radius = √(area/π) Circumference = 2 × π × radius = 2 × π × √(area/π) = √(2² × π² × area/π) = √(4 × π × area)
What happens to the area of a circle when the radius is doubled tripled?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
How do you find the diameter of a circle if they give you the area?
Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)
What happen to the area of circle when the radius is tripled?
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
How do you find the diametre if you have the area?
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
What is a radius square?
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
