Question

The official Wilson basketball of the NCAA has a diameter of approximately 9 inches. Calculate both its approximate surface area and its approximate volume. Please round your answer to the nearest hundredths place. (3 points)

Answer 1

Do you know the formula for how to find the surface area and volume of a sphere? :)

Answer 2

well.. here are some hints:

#1 : Note that diameter = 2* radius (r)
In simple terms diameter = double radius. Therefore radius = 1/2 diameter.

#2: Surface area of a sphere (since your finding the surface area of a basketball) is given by the formula:


#3: Volume of a sphere is given by the formula:

Use these and you'll be fine
