Question

A birthday cake is being made using a cylindrical baking pan. The radius of the pan is 4 inches, and the height is 5 inches. Which formula represents the correct way to calculate the volume of the cake?

Answer 1

im pretty sure the answer is D.

Answer 2

Formula used : Volume of cake =
`\pi r^2h`

Volume of cake is
`251.2`inches³

Explanation:

Given : A birthday cake is being made using a cylindrical baking pan. The radius of the pan is 4 inches, and the height is 5 inches.

We have to find the formula that represents the correct way to calculate the volume of the cake.

Since, the cake is in shape of cylindrical.

Thus, Volume of cylindrical =
`\pi r^2h`

Since, given radius = 4 inches.

and height = 5 inches

Thus, Volume of cake =
`\pi (4)^2\cdot 5`

Simplify, we have,

Thus, Volume of cake =
`80\pi`

Using π = 3.14

Volume of cake is
`251.2`inches³
