Question

Find the Perimeter & Area for the following circle.

use 3.14 for Pi
Round to the tenths place

Answer 1

Explanation:

Answer 2

A = 28.3 cubic inches; P = 20.1 inches

Explanation:

Looks like 3/4 of a full circle

The area of a circle is calculated with the formula:
`\pi r^(2)`

Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.

The radius is given as 3 inches

Area =
`3.14*3^(2) = 3.14*9 = 28.26` cubic inches = 28.3 cubic inches

------------------------

Perimeter is calculated with
`2\pi r`.

But this is 3/4 of a circle with an additional two 3-inch sides

Perimeter =
`(3)/(4)*2\pi r` + 2(3) = 14.1 + 6 = 20.1 inches
