Question

There are many cylinders with a height of 18 meters. Let r  represent the radius in meters and V represent the volume in cubic meters.

a. Write an simplified equation (plugging in all know quantities) in terms of   (meaning do not
        multiply by 3.14 when you simplify) that represents the volume as a function of the radius.
​

Answer 1

18pir^2

Explanation:

Answer 2

The equation would be:
`V(r)=2\pi r \cdot 18`

Volume V is represented as a function of radius r. Height of a cylinder h is multiplied by the circumference of the cylinder 2πr to result in volume.
