 $\begin{array}{r} r = & 3.14 \end{array}$

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 $r = 3.14$ into the formula for the area of a circle. Pi $π$ is approximately equal to $3.14$ .

$π \cdot {3.14}^{2}$

Step 3

Raise $3.14$ to the power of $2$ .

$π \cdot 9.8596$

Step 4

Multiply $π$ by $9.8596$ .

$30.97484692$
