Find the Area circle (2)

 $\begin{array}{r} r = & 2 \end{array}$

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 $r = 2$ into the formula for the area of a circle. Pi $π$ is approximately equal to $3.14$ .

$π \cdot 2^{2}$

Step 3

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

$π \cdot 4$

Step 4

Move $4$ to the left of $π$ .

$4 π$

Step 5

The result can be shown in multiple forms.

Exact Form:

$4 π$

Decimal Form:

$12.56637061 \dots$
