 $\begin{array}{r} r = & \frac{1}{6} \end{array}$

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 $r = \frac{1}{6}$ into the formula for the area of a circle. Pi $π$ is approximately equal to $3.14$ .

$π \cdot {(\frac{1}{6})}^{2}$

Step 3

Step 3.1

Apply the product rule to $\frac{1}{6}$ .

$π \cdot \frac{1^{2}}{6^{2}}$

Step 3.2

One to any power is one.

$π \cdot \frac{1}{6^{2}}$

Step 3.3

Raise $6$ to the power of $2$ .

$π \cdot \frac{1}{36}$

Step 4

Combine $π$ and $\frac{1}{36}$ .

$\frac{π}{36}$

Step 5

The result can be shown in multiple forms.

Exact Form:

$\frac{π}{36}$

Decimal Form:

$0.08726646 \dots$
