Question

What is the volume of a hemisphere with a radius of 42.1 ft, rounded to the nearesttenth of a cubic foot?

Answer 1

Let's recall the formula of the volume of a sphere:

Volume = 4/3 * π * r3

Now, we can calculate the volume of a hemisphere that is half of a sphere:

Volume = 2/3 * π * r3

Now, we can replace the value of the radius given, as follows:

Volume = 2/3 * π * 74,618.46 cubic feet

Volume = 154,639.3 cubic feet
