Question

The diameter of a circle is 13inches . What is the circle's area? Use 3.14 for ​

Answer 1

Explanation:

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

Where r is the radius which is half of the diameter. In that case, r is equal to 6.5.

`\pi` in this case, is approximated to be 3.14

So the area is
`3.14 * (6.5)^2 = 132.665`

So the circle's area is 132.665

Hope that helps!
