Atennis ball has a diameter of 2.7 inches. round your answer to the nearest hundreth of an inch. use pi = 3.14.

Hi Brennan! To solve your equation, you just need to find the radius of it first.

Find the radius 'r'.
The "/" sign indicates a fraction
r = d/2
r = 2.7/2
r = 1.35

Then you try to find the surface area and round your answer to the nearest hundredth of an inch.

S = 4 (pi) r^2
S = 4 (pi) (1/35)^2
S = 7.29 (pi)
S ≈ 22.89

The surface area of the tennis ball is about 22.89 in^2. Hope this helped!
