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
Just doing this to get points... :(
Yes, substitute a=2.
14 - 4 + 6 - 6 = -2
8 - 10 = -2
M+15=65 could this be the answer you are possibly looking for? if the m is Mai's savings "increased by 15" would simply be adding 15 and it would be equal to 65
