Question

What is the area of a circle with a radius of 3 cm?

Answer 1

`Area = 28.27cm^2`

Explanation:

The area of a circle can be obtained by using the equation below:

where the mathematical constant, `pi`, has a value of approximately 3.14 and `r` represents the radius of the circle.

All we have to do is square the given radius and multiply that value by `pi` to figure out the area:

`Area = (3cm)^2 xx pi`
`Area = 28.27cm^2`
