Question 1180711


the surface of a basketball is 576π cm². How far does this basketball travel if it makes 4 complete rolls?

it will travel 4 times the perimeter around the diameter

area = 576pi = 4pi r^2

576/4 =r^2

144 =r^2

r = 12 ie the radius

diameter =12

Circumference = pi *  d

12 pi

4 rolls
48 pi cm is the distance it travels
