Explanation:

find the area of the circle by multiplying the radius by pi(3.14) then you would subtract that from the area of the rectangle. Hope this helps

Answer 2

hee-hee!

Explanation:

We know that the circles diameter is 15 mm. We can tell that by looking at the side of the rectangle. It says 15 mm.

Either way, we use the formula to find the area of a circle:

A =

A = (3.14)(15)

A = 47.1

The area of the circle is 47.1. (i think?)
