Question

A circular plate has a radius of 7 inches. Which is closest to the area of the plate?

Answer 1

Approximately
`153.94`
`in^2`

Explanation:

Recall the formula for the area of a circle:

`\pi r^2`

Where r is the radius.

We are given that the radius is 7 inches. Let's plug that into our formula and solve it. We have:

`\pi r^2=\\\pi (7)^2=\\\pi (49)=\\49\pi`

From here, we multiply our answer by pi using a calculator and round.

• Using a calculator, we can find that
  `49\pi` is approximately 153.93804 (round to the nearest hundredth: 153.94)
