Question

Find the surface area of a smooth golf ball with the minimum diameter allowed by the United States golf association

Using theses numbers 1.680,3.14

Answer 1

surface area o fthe ball = 4 * 3.14 * radius^2

if diameter = 1.680 then radius = 1/2 * 1.680 = 0.84

so surface area = 4 * 3.14 * 0.84^2 =  8.862
