Question

Francisco is making an effort to drink more water, and has set a goal of 222 liters per day. He wants to know the volume of the water bottle he takes to school each day. The water bottle has the dimensions shown in the diagram.

Radius 4

Height 20 What is the volume of Francisco's water bottle?

Answer 1

V = 1,005.7 rounded off to one decimal place

Explanation:

Volume of a cylinder = πr²h

V = 22/7 x 4 x 4 x 20

V = 1,005.7

Answer 2

The answer is 1004.8

Explanation:

Ok, so the formula for a cylinder is π times radius^2 times the height. In our case, our radius is 4 and our height is 20.

π×4^2×20

3.14×16×20

We then get 1004.8 as our answer.

I hope this helps :)
