A cylinder-shaped water tank is 160 cm tall and measures 87.92 cm around.



What is the volume of the water tank?


Enter your answer as a decimal in the box. Use 3.14 for π.

Answer 1

Explanation:

The volume formula for a cylinder is

`V=\pi r^2h`

In order to find the radius we need to use the circumference we were given. The formula for the circumference is

`C=2\pi r`

Filling in the info about the circumference value of 87.92:

`87.92=2(3.14)r` or

87.92 = 6.28r so

r = 14

Now that we know the radius we can fill in the volume formula:

`V=(3.14)(14)^2(160)` and

V = 98470.4 cm cubed
