Question

The radius of a circle is 3 feet. What is the circle's area? Use 3.14 for ​.

Answer 1

Answer:
`A = 28.26 ft^2`

Explanation:

The formula for the area of a circle is: A = π
`r^2`

We need to plug in the values from the question into the formula.

• r = 3 feet
• use 3.14 for π

`A = (3.14)(3)^2`

A = (3.14)(9)

A = 28.26

Don't forget the units! Since we found the area of the circle, we need to square the units.

`A = 28.26 ft^(2)`
