Answer: the height is 18 cm.
Step-by-step explanation:
The equation for the volume of a cone is the following: V = 1/3 × B × h, where B (base) = πr². Because we are given the radius of the base, but not the base’s area itself, we will use V = 1/3πr²h.
Here, we are trying to solve for h, the height, so first we can first rearrange the equation to solve for h:
1) V = 1/3πr²h
2) h = V ÷ 1/3πr² (divide both sides by 1/3πr²h)
Now, we just need to input the given values: V = 471, π = 3.14, r = 5
h = 471 ÷ 1/3(3.14)(5²)
= 471 ÷ 1/3(3.14)(25)
= 471 ÷ 1/3(78.5)
= 471 ÷ (78.5/3)
= 18 cm
