Answer:

254.47 in²

Explanation:

Hello!

Recall that the area of a circle is represented by the formula:
A = \pi r^2

The radius is r.

We have the radius, 9in, so simply plug it into the formula to solve for the area.

Solve for the area:

  • A = πr²
  • A = π(9in)²
  • A = 81in²π
  • A = 254.4690049408 ≈ 254.47in²

The area is approximately 254.47²in.
