Find the Area circle (7.5)

 $\begin{array}{r} r = & 7.5 \end{array}$

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 $r = 7.5$ into the formula for the area of a circle. Pi $π$ is approximately equal to $3.14$ .

$π \cdot {7.5}^{2}$

Step 3

Raise $7.5$ to the power of $2$ .

$π \cdot 56.25$

Step 4

Multiply $π$ by $56.25$ .

$176.71458676$
