Answer:

225pi

Step-by-step explanation:

area = r * r *  π

==> area = 225π

Answer:

A = 225[tex]\pi[/tex] or A = 706.858

Step-by-step explanation:

The formula to find the area of a circle is A=[tex]\pi r^{2}[/tex], with r being the radius.

In this case, 15 is your radius, so you just replace r with 15, like so:

A=[tex]\pi 15^{2}[/tex], then simplify [tex]15^{2}[/tex]

A = [tex]225\pi[/tex]

From here you can leave the answer in its exact form, [tex]225\pi[/tex], or you can simplify it by multiplying 225 times pi. In that case, your answer would be: 706.858 (rounded to the thousanths place).
