\begin{array}{r} r = & 6 cm \end{array}

$\begin{array}{r} r = & 6 cm \end{array}$

Step 1

The area of a circle is equal to Pi

π

$π$ times the radius

r

$r$ squared.

π \cdot {(r a d i u s)}^{2}

$π \cdot {(r a d i u s)}^{2}$

Step 2

Substitute in the value of the radius

r = 6

$r = 6$ into the formula for the area of a circle. Pi

π

$π$ is approximately equal to

3.14

$3.14$ .

π \cdot 6^{2}

$π \cdot 6^{2}$

Step 3

Raise

6

$6$ to the power of

2

$2$ .

π \cdot 36

$π \cdot 36$

Step 4

Move

36

$36$ to the left of

π

$π$ .

36 π {(cm)}^{2}

$36 π {(cm)}^{2}$
