Question

The distance around a circle is 37.7 meters long. What is the area of the circle?

Answer 1

≈ 113.16

Explanation:

The circumference of a circle (the distance around) is equal to
`\pi` * diameter

`\pi * diameter = 37.7`

`(\pi )/(\pi ) *diameter = (37.7)/(\pi )`

diameter = 12.006

radius = diameter / 2

radius = 6.003

The area of a circle is
`\pi r^(2)`

`\pi 6.003^(2)`

= 113.16
