Answer:
a: 18pi
b: 3pi
Step-by-step explanation:
part a:
total area = 12^2*pi = 144pi
144pi/8 = 18pi
part b:
total circumference = 12*2*pi = 24pi
24pi/8 = 3pi
The correct answer is B.

is greater then one, 9/10 is only slightly less than one, 2/3 is a little more than half, and 1/8 is the smallest number.
