Find the Area circle (16cm)

 $\begin{array}{r} r = & 16 cm \end{array}$

The area of a circle is equal to Pi $π$ times the radius $r$ squared.

$π \cdot {(r a d i u s)}^{2}$

Substitute in the value of the radius $r = 16$ into the formula for the area of a circle. Pi $π$ is approximately equal to $3.14$ .

$π \cdot 16^{2}$

Raise $16$ to the power of $2$ .

$π \cdot 256$

Move $256$ to the left of $π$ .

$256 π {(c m)}^{2}$
