Question

During play, a ball with a diameter of 3.00 inches splits exactly in half. What is the volume of each portion of the ball?

Answer 1

Hello there!
The answer to your question is A. 1.75 in.³
The ball split, so now the diameter is 1.50 in. The radius is always half of the diameter. So now, do the volume formula for a sphere. You answer should turn out to be A.
Hope I helped!

Answer 2

Use this formula V=4/3(pie)r^3 the radius is 1.5 
V=(4/3)(3.14)(1.5^3)
=14.10
now divide that in half and you get 
7.05 cubic inches
