Question

What is the approximate volume of a cylinder with a radius of 3 ft and a height of 4 ft?

Use 3.14 to approximate pi.
Express your answer in hundredths.

______ft3

Answer 1

`V = \pi r^(2) h = 3.14 * 3^(2) * 4 = 113.04`

Answer 2

The formula for the volume of a cylinder is pi x radius^2 x height, so after substituting the values, we get 3.14 x 3^2 x 4. First, we find the value of 3^2, which is 9. 3.14 x 9 equals 28.26, so now we have 28.26 x 4, which gives us 113.04. So the volume of the cylinder is 113.04. :)
