The volume of a cylinder is given by :
r is the radius of the base of a cylinder
h is height of cylinder
The height of a cylinder is twice the radius of its base. It means that h = 2r
So, volume of cylinder becomes :
So, the volume of the cylinder is given by the expression .
Answer:
-12
Step-by-step explanation:
Plug in 5 for m:
Solve:
The expression is -12
1 + 3n + 7n = 7(n + 4) + 6(3n + 3)
1 + 3n + 7n = 7n + 28 + 18n + 18
10n + 1 = 25n +46
25n - 10n = 1 - 46
15n = -45
n = -45/15
n =-3
