Answer:
son = 6 mother = 48
Step-by-step explanation:
Mother = m
son = s
m = 8s
m+6 = 9/2 * (s+6)
so
2(8s + 6) = 9(s +6)
16s + 12 = 9s + 54
16s - 9s = 54 - 12
7s = 42
s = 42/7 = 6 years old
so the mother is 8s = 8*6= 48 years old

Answer:
C = 28.048
Step-by-step explanation:
Circumference = 2pi(r)
Area = pi(r)^2
62.6 = pi(r)^2
r^2 = 62.6/pi
r^2 = 19.926
r = 4.464
Therefore, circumference = 2pi(4.464)
= 28.048
