A men's basketball is about 24.3 centimeters in diameters , while the diameter of a women's basketball is about 23.4 centimeters. What is the ratio of the surface area of a men's basketball to the surface area of a women's basketball? Round to the nearest tenth.

thank you again

surface area is directly proportional to area, which is direcly proportional to the square of the radius.

ASmens/SAwomen= ( (24.3/2 /23.4/2))^2
= (24.3/23.4)^2=

Put this in your google search window:
(24.3/23.4)^2=
the surface area is proportional to the square of the diameter

M / W = (24.3 / 23.4)^2
