The surface area of a golf ball is 8.92 in ^2. The surface area of a softball is 53.78. Find the ratio of the volumes of a golf ball to a softball. Surface Area = 4π r^2 and Volume = 4/3π r^3
I don't understand this problem, could someone please help me?
volume=4/3 PI r^3
now how do you get the radius?
r= sqrt (SA/4PI)= k*sqrtSA
so ratiovolumes= (k*sqrtSAgolf/ksqrtSAsoft)^3=
= (sqrt (8.92/53.78))^3
So is my answer 496.479489?
