$\begin{array}{r} r = & 50 \end{array}$

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

$r = 50$ into the formula for the area of a circle. Pi

$π$ is approximately equal to

$3.14$ .

$π \cdot 50^{2}$

Step 3

Raise

$50$ to the power of

$2$ .

$π \cdot 2500$

Step 4

Move

$2500$ to the left of

$π$ .

$2500 π$

Step 5

The result can be shown in multiple forms.

Exact Form:

$2500 π$

Decimal Form:

$7853.98163397 \dots$
