A leather ball has a diameter of 28.4 cm. Which is the area of the piece of leather used on the surface of the ball?

has the same diameter as the sphere, and height equal to its diameter ... The surfce area of a soccer ball is 250 square inches ... An official basketball has a radius of 12.5 cm and ... much leather is required to cover 12 official.

2534 cm^2 to the nearest whole number.

Step-by-step explanation:

The ball is a sphere whose surface are is 4 pi r^2

The radius r = 1/2 diameter = 1/2 * 28.4

= 14.2 cm.

The required area = 4 * pi * 14.2^2

= 2533.88 cm^2
