Problema Solution
V= 4/3 3.14 r3 gives the volume of a sphere with radius r find the volume of a sphere with radius x+9
Answer provided by our tutors
V= (4/3)*3.14*r^3
r = x + 9
V= (4/3)*3.14*(x + 9)^3
V = (12.56/3)*(x + 9)^3
V = (12.56/3)*(x^3 + 27x^2 + 243x + 729)
V = (12.56/3)*x^3 + 113.04*x^2 + 1017.36*x + 3052.08
