The area of a circle is found by the equation pi times r2. To calculate the radius from the area we need to divide the area by pi and get the square root of the result.
if we use 3.1418 as a close approximation of pi, we get 706.9 ÷ 3.1418 = 225 and the square root of 225 = 15.
The area of a circle is 153.86cm².find the radius of the circle
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.
A circle with a radius of 4 cm has an area of 50.27 square cm.
The area of a circle with a radius of 7 cm is: 153.9 cm2
The area of any circle is (pi) x (radius)2 .The area of half the circle is just half of that number.
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
A circle with a radius of 135 units has an area of 57,255.53 square units.
A circle with a radius of 10m has an area of 314.16 m2
The area of a circle with a radius of 2m is: 12.566 m2
The radius of a circle when the area is 96 is 5.528
The area of a circle if the radius is 7yd is 153.9yd2
If the area of a circle is 40.7 the radius is: about 3.6 (3.599)
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
