Total area of circle: 360/190 times 662.89/1 = 1256 rounded to the nearest integer
Radius of the circle = square root of 1256/pi = 20 rounded to the nearest integer
662.89 = 66289/100 in fraction
The area of the sector of a circle with a radius of 2 inches and an arc of 60 degrees: 2.094 square inches.
It depends on what information you have: the radius and the area of the sector or the length of the arc.
Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees
The area of the sector is: 221.2 cm2
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
From your question, we can't tell whether [ 64 pi ] is the area of the circleor the sector.The area of a circle is [ pi R2 ].If [ 64 pi ] is the area of the circle, then the radius is [ 8 ], and we don't careabout the sector.If [ 64 pi ] is the area of the sector, then the area of the full circle is [ 256 pi ](because the 90-degree sector is 1/4 of the circle), and the radius is [ 16 ].
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm
If you mean a sector with an arc of 110 degrees and an area of 50 square units Area of all the circle: 360/110 times 50 = 163.'63' square units Radius of the circle is the square root of 163.'63'/pi = 7.2171377402 So the radius of the circle is about 7 units
There are 360 degrees in a circle so it will be 1/3 of pi*62 square units
There are 360 degrees in any circle. The radius doesn't matter.
The area of the sector of the circle formed by the central angle is: 37.7 square units.
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.
The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared Radius of a circle = diameter/2 Degrees around a circle = 360 degrees
Area of a sector of a circle = (pi) x (radius)2 x (central angle of the sector / 360)
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
0. There is no circle so no shaded area of a circle!
The sector isn't a question, and there's no answer to it. There are a fewnumbers that describe it, however, and they can be calculated like this:-- The circumference of the circle is (pi) x (diameter) = 12 pi cm-- The area of the circle is (pi) x (radius)2 = 36 pi cm2-- 120 degrees is 1/3 of the circle.The length of the arc of the sector is 12 pi/3 = 12.5664 cm (rounded)The area of the sector is 36 pi/3 = 37.6991 cm2(rounded)
The area of a circle is derived from Pi x r2 where Pi = 3.14 and r = the radius, therefore a circle with an area of 662.89 has a radius of 14.5
