Question

A cylindrical cookie jar has a volume of 904.23 cubic inches. It is 8 inches tall. What is the radius of the cookie jar? Round your answer to the nearest inch.​

Answer 1

Answer:

r = 6 in

Explanation:

The volume of a cylinder of radius r and height or length h is

V = πr²h.

Here, we need to solve for the radius; we get:

V

------------- = r²

πh

904.23 in³

This works out to r² = ----------------- = 35.97 in²

π(8 in)

Finally, take the square root of this result to find the radius, r:

r = √35.97 in² = 6 inches
