Explanation

Answer

Problem

Find the area of a circle with a radius of 9 meters.

Step

The given values are

r = 9 m

Formula

The area of circle is

\$ A = πr^2\$

Step

Substitute the values

\$A = π times (9)^2\$

Step

After simplification

\$A = π times 81\$

Step

After simplification

A = 81π

Step

The area of the circle is 81π.
