Question

If the radius of a circle is 1 kilometer what is the area of the circle?

Answer 1

The area of the circle is
`1\pi` or approximately 3.14
`km^2`

Explanation:

The formula to find the area of a circle is
`\pi r^2`, where
`r` represents the radius of the circle. In this case, the area would be
`1^2*\pi` =
`\pi` ≈ 3.14
`km^2`.
