A typical baseball has a diameter of about 7.3cm. Which of the following is the best estimate for the volume of a baseball in cubic cm?

Question

I am in danger of failing in my math class. I am in 7th grade but they put me in 8th when I barely know alot about math.

Answer 1

d = 7.3 cm

r = half of diameter = 3.65 cm

Volume of sphere = (4/3)(pi)r³ 

If you want this answer in decimals, so all you have to do is calculate, using pi = 3.1416.

Take out your calculator to compute the volume, which will be in cubic centimeters.
