A bowling ball cannot weigh more than 16 pounds and must have a diameter of 8 1/2 inches. How many square inches are in the surface area of a bowling ball before the finger holes are drilled? Express your answer as a common fraction in terms of pi.

The weight given in this question is irrelavent....not needed....

 

The surface area of a sphere (bowling ball)   4 pi r^2

You are given DIAMETER...use 1/2 of this for the RADIUS   then   4 pi r^2    in^2

   Can you take it from here?
