Exercise 30 Page 267

Substitute the given values into the formula for the radius.

≈ 2.5 inches

We are asked to find the radius of a cylindrical container of chocolate drink mix with a volume of 162 cubic inches and a height of 8.25 inches.

To do so, we will use the given formula. r = sqrt(V/π h) Let's substitute 162 for the volume V and 8.25 for the height h into the formula to find r.

r = sqrt(V/π h)

V= 162, h= 8.25

r = sqrt(162/π ( 8.25))

Use a calculator

r = 2.500089...

Round to 1 decimal place(s)

r ≈ 2.5

The radius of the cylindrical container is about 2.5 inches.
