Question

A circle with diameter 11 inches.

What is the approximate area of the circle? Use 3.14 for Pi and round the answer to the nearest tenth.
17.3 in2
34.5 in2
95.0 in2
379.9 in2

Answer 1

95.0 in²

The question and proof is below

Answer 2

a=95.0 in^2

Explanation:

The area of a circle is:

a=
`\pi`r^2

First, we must find the radius

r=d/2

r=11/2

r=5.5

Substitute 5.5 in for r in the formula

a=
`\pi`5.5^2

a=
`\pi`30.25

Substitute 3.14 in for pi

a=3.14*30.25

a=94.985

Rounded to the nearest tenth:

a=95.0 in^2

Hope this helps! :)
