Question

Find the area of the circle. Give your answer to two decimal places.

Answer 1

The area of a circle can be found using the formula:

`A=\pi r^2`

Where r represents the radius of the circle.

On the other hand, the radius of the circle is the distance between the center of the circle and its circumference. The radius of the given circle is 20. Substitute r=20 to find the area of the circle:

`\begin{gathered} A=\pi(20)^2 \\ =400\pi \\ =1256.637\ldots \end{gathered}`

Up to two decimal places, the area of the circle is:

`1256.64`
