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

Answer:

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

Step-by-step 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

$100=(3.14)(2^{2})h$

$100=12.56h$

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