Question

A cylindrical oil drum has a diameter of 2 feet and a height of 3 feet. What is the volume of the oil drum?

Answer 1

cylindrical volume

`= \pi{r}^(2) h`

Radius of the cylindrical

2ft ÷ 2 = 1.5ft

`3.142 * {1.5}^(2) * 3 \\ = 3.142 \: * 2.25 * 3 \\ = 7.0695 * 3 \\ = 21.2085 \\ = 21.21(2d.p.)`
