Hey there!

The answers are 706.5 and 1589.625

The formula for the area of a circle is
\pi
r^2.

For the first circle, the radius is 15, so let's solve:


\pi (15^2)


\pi(225)\\3.14(225)\\\\706.5

The second circle has a diameter of 45, and the radius is half the diameter, so 45/2 = 22.5. Let's solve:


\pi (22.5^2)\\\pi (506.25)\\3.14(506.25)\\1589.625

Have a super awesome day!
