The volume of a sphere is
The radius is 6.1 and
= 3.14, now let's plug it into the equation

Thus the volume is 950.3
Hope that helps!
Answer:
-3/5
Step-by-step explanation:
(b + 14)/a = ((-5) + 14)/(-15) = -9/15 =-3/5
X + (2 + x) + (4 + x) = 60
3x + 6 = 60
3x = 54
x = 18
x + 2 = 20
x + 4 = 22
Their ages are 18, 20, 22
