Question

The radius of a cylindrical water tank is 4.5ft , and its height is 13ft . What is the volume of the tank? Use the value 3.14 for π , and round your answer to the nearest whole number. Be sure to include the correct unit in your answer

Answer 1

Answer: 827 cubic feet

Explanation:

The volume of a cylinder is given by :-

`\text{Volume}=\pi r^2 h`, where r is radius and h is height of the cylinder.

Given : The radius of a cylindrical water tank is 4.5 ft , and its height is 13ft .

Then , the height of the cylinder will be :-

`\text{Volume}=(3.14)(4.5)^2(13)\\\\\Rightarrow\ \text{Volume}=826.605\approx827\text{cubic feet}`

Hence, the volume of the tank = 827 cubic feet
