\begin{matrix} r = & 150 \end{matrix}

$\begin{array}{r} r = & 150 \end{array}$

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 = 150

$r = 150$ into the formula for the area of a circle. Pi

π

$π$ is approximately equal to

3.14

$3.14$ .

π \cdot 150^{2}

$π \cdot 150^{2}$

Step 3

Raise

150

$150$ to the power of

2

$2$ .

π \cdot 22500

$π \cdot 22500$

Step 4

Move

22500

$22500$ to the left of

π

$π$ .

22500 π

$22500 π$

Step 5

The result can be shown in multiple forms.

Exact Form:

22500 π

$22500 π$

Decimal Form:
