A bosu® ball in the shape of a hemisphere (half of a sphere)
The diameter of the ball is 58 centimeters and is completely filled with air.
How much air does the ball contain, in cubic centimeters? Round your answer to the nearest centimeter. (Use 3.14 for π.)

diameter is the measure of the circular end/bottom so divide that by 2 to get your radius and use the volume formula of a sphere and multiply that by half.
I don't get it.
Volume of a sphere:
V = 1.3333 * pi * r^2
Find that volume. The divide it in half to find the volume of the hemisphere.
V = 1.3333 * pi * r^2
Find that volume. The divide it in half to find the volume of the hemisphere.
