Find the radius of a circle with circumference of 20pi. 2.Find the radius of a circle with the circumference of 64pi 3.If the area of a circle is 9pi, find the radius.
The key lies in the size of the angle. The area of its sector is 80cm sq. This area is a fraction of the area of the whole circle: 125/ 360. So, 80 x 360/125.
how to find radius of a circle from area
Calculate the radius, diameter, circumference, area & volume of a.The area of a circle is 64(pie). Find the radius of the circle.
SOLUTION: find the circumference and area of a circle with diameter.
If the area of the circle is 64(pie) then the radius of the circle must be 8. area(a) = the complete diameter of the circle, which is 64 radius(r) = only half.
As the size of the circle changes, the area is recalculated. A circle is. If you know the diameter of a circle, the area inside it can be found using the formula.
