Question

A cylinder shaped drum is used as a garbage container. The drum has a height of 4 ft and a radius of 1.25 ft.

Answer 1

V=hpir^2
h=4
r=1.25
v=4pi1.25^2
v=4pi1.5625
v=6.25pi
v=19.625
rounded to hundreth
v=19.63 ft³

Answer 2

Answer: 19.63 cubic feet

Step-by-step 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.
