Question

Use the value 3.14 for it, and round your answer to the nearest whole number:

Answer 1

The volume of a cylinder is given by

`V=\text{ ( Area of the circle)}* height`

In our case, the area of the circle is given by

`\begin{gathered} A=\pi\cdot r^2 \\ A=(3.14)(2^2) \\ A=12.56ft^2 \end{gathered}`

Since the height is equal to 21 ft, the volume is given by

`\begin{gathered} V=(12.56)*21 \\ V=263.76ft^3 \end{gathered}`

Therefore, by rounding this result to the nearest whole, the answer is: 264 cubic feet
