Find the Area circle (12cm)



$\begin{array}{r} r = & 12 cm \end{array}$

Step 1

The area of a circle is equal to Pi

$π$ times the radius

$r$ squared.

$π \cdot {(r a d i u s)}^{2}$

Step 2

Substitute in the value of the radius

$r = 12$ into the formula for the area of a circle. Pi

$π$ is approximately equal to

$3.14$ .

$π \cdot 12^{2}$

Step 3

Raise

$12$ to the power of

$2$ .

$π \cdot 144$

Step 4

Move

$144$ to the left of

$π$ .

$144 π {(cm)}^{2}$
