I’m really unsure of how to do this problem and need some help. The image shows a large shaded circle with a smaller unshaded circle inside. It reads, "This figure consists of 2 concentric circles. If the shaded area is 64 (pi) sq. in. and the smaller circle has a radius of 6 in., what is the radius, in inches of the larger circle?" I wasn’t at school today and I have a little work done (as shown in the photo), but I’m really struggling and I have no clue what to do. Thanks for the help!!
