area =color(blue)(706.5 cm^2

#### Explanation:

The area of a circle is given by formula
color(blue)(pi(r)^2

Where the radius is denoted by $r$ and $\pi$ is a constant having value $3.14$

We have radius as $r = 15$

So area = $3.14 \times {\left(15\right)}^{2}$

=color(blue)(706.5 cm^2(assuming units to be in cm)
