Question

What is the area of a circle with a radius of 4

Answer 1

Answer: 16π units²

Step-by-step explanation: To find the area of of a circle, let's first start by writing down the formula for the area of a circle.

Area =
`\pi r^(2)`

Since we are given the radius of the circle, we can plug 4 into our formula.

Area =
`\pi (4^(2))`

4² is equal to 4 x 4 which is 16.

Area = 16
`\pi units^(2)`

Therefore, the area of the circle is 16π units².
