Answer:
V = 72π in ^3
Step-by-step explanation:
The volume of a cylinder is given by the formula
V =pi r^2 h
We know the height is 8 and the diameter is 6
We need to find the radius
d= 2r
6= 2r
6/2 = 2r/2
3 =r
We can substitute in. We must keep pi as pi to be exact,
V = pi * 3^2 *8
V = pi * 9*8
V =72 pi
V = 72π in ^3
Answer:
72[tex]\pi[/tex] inches^3
Step-by-step explanation:
The formula for the volume of a cylinder is V = [tex]\pi r^2h[/tex], where r represents the radius of the cylinder (radius is the length of half the diameter) and h represents the height of the cylinder).
The question gives the diameter of the cylinder, so to find the radius the diameter would have to be divided by 2.
- 6 / 2 = 3
The radius of the cylinder is 3 inches. The height of the cylinder is already given, so we can proceed in finding the volume of the cylinder using the formula V = [tex]\pi r^2h[/tex].
Substitute 3 for r and 8 for h.
- V = [tex]\pi (3)^2(8)[/tex]
Start by evaluating the exponent.
- V = [tex]\pi (9)(8)[/tex]
Multiply 9 and 8 together.
- V = [tex]\pi (72)[/tex]
The question is looking for the exact answer, therefore the answer would just end here. The final and most exact answer is 72[tex]\pi[/tex] inches^3 (which is 226.194671 inches^3 or if rounded, 226.19 inches^3).
