Answer:
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.
Step-by-step explanation:
2534 cm^2 to the nearest whole number.
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
