What is the volume of a hemisphere with a diameter of 7.1 ft, rounded to the nearest tenth of a cubic foot?

The volume of the hemisphere is:  93.7  cubic feet

Step-by-step explanation:

Recall that the volume of a sphere of radius R is given by:

therefore, the volume of a hemisphere would be half of such:

Now,the radius of the hemisphere must be half of its diameter, that is:

7.1 ft /2 = 3.55 ft

Now, when we use this value in the hemisphere's volume formula, we get:

Which rounded to the nearest tenth gives:  93.7  cubic feet
