Answer:
C=diameter x pi
radius + radius = diameter
6+6=12
12 x 3.14 = 37.68
8 x 3.14 = 25.12
_____________
Radius x radius x pi = area
diameter / 2 = radius
8/2=4
4 x 4 = 16 x 3.14 = 50.24
6 x 6 = 36 x 3.14 = 113.04
_______________
6 km circle has circum of 37.68 and area of 113.04
8 km circle has circum of 25.12 and area of 50.24
