What is the volume of a cylinder, in cubic ft, with a height of 9ft and a base diameter
aev [14]

Answer:

Volume of cylinder is: Volume=1808.64 ft³

Step-by-step explanation:

Height of cylinder = 9 ft

Base diameter of cylinder = 16 ft

We need to find volume of cylinder .

The formula used is: Volume=\pi r^2h

We need radius:

The radius = diameter/2 = 16/2 = 8 ft

Putting values and finding volume of cylinder

Volume=\pi r^2h

Volume=3.14\times (8)^2\times (9) \\Volume=3.14\times 64\times (9) \\Volume=1808.64 \: ft^3

So, Volume of cylinder is: Volume=1808.64 ft³
