Find the area of the great circle of the ball if its radius is 8 cm.

A ball is a set of points in space located at the same distance from the center.

The largest circle of a ball is the plane passing through its center.

To calculate its area, we use the formula for the area of a circle, according to which the area of the cruise is equal to the product of the radius of the circle in a square by the number PI:

S = πr ^ 2;

S = 3.14 * 8 ^ 2 = 3.14 * 64 = 200.96 cm2.

Answer: the area of the larger circle of this ball is 200.96 cm2.
