Question 7
Find the volume.

Answer 1

A: 686π≈2,156

Explanation:

First, you need to find the area of the circle then times that by 14.

π
`r^(2)` Formula for the area of a circle

π
`7^(2)` r stands for radius, so you divide the diameter by 2 and get 7.

π49 This is the area of the circle

π49×14 Now multiply by 14

=686π This is your answer.

=2155.13256 When you times it by pi this is what you get

=2156 This is your answer if you want it rounded up
