Question

A bird feeder is in the shape of a cylinder. It has a volume of about 100 cubic inches. It has a radius of 2 inches. What is the approximate height of the bird feeder? Use 3.14 for pi. Math item stem image CLEAR CHECK 4 inches 8 inches 12 inches 79 inches

Answer 1

8 inches because 3.14*2^2*8=100.48 which is rounded to 100

Answer 2

The approximate height of the bird feeder is
`8\ in`

Explanation:

we know that

The volume of a cylinder is equal to

`V=\pi r^(2)h`

In this problem we have

`V=100\ in^(3)`

`r=2\ in`

substitute and solve for h

`100=(3.14)(2^(2))h`

`100=12.56h`

`h=100/12.56=7.96=8\ in`
