Question

9. packaging a juice manufacturer is creating new cylindrical packaging. the

height of the cylinder is to be 3 inches longer than the radius of the can. the
cylinder is to have a volume of 628 cubic inches. use 3.14 for pi
a. write a polynomial equation to support the model.

Answer 1

Let the radius be
`r` inches. Then, the height is
`r+3` inches.

Using the formula for the volume of a cylinder, it follows that
`\boxed{3.14r^2(r+3)=628}`.
