37.68 sq cm

Answer 1

The first question I don't really know how to do, but the second one I do. The answer to the second question is 113.04. So what you do in order to get the area of a circle when you know the radius is by using the following formula: A=πr^2. In this case, you have a circle's radius of 6. You take 6 and square it, then multiply it by 3.14 and get 113.04.

Hope this helps!!!!
