Answer 1

19.63

Explanation:

Answer 2

Answer: 19.63 cubic feet

Explanation:

The volume of cylinder is given by :-

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

Given: The radius of the cylinder shaped drum= 1.25 ft.

The height of the cylinder shaped drum= 4 ft

The volume of cylinder shaped drum is given by :-

`\text{Volume}=\pi (1.25)^2(4)\\\\\Rightarrow\text{Volume}=(3.14)(1.25)^2(4)\\\\\Rightarrow\text{Volume}=19.625\approx19.63\ ft^3`

Hence, the drum hold 19.63 cubic feet garbage.
