Answer:
A
Step-by-step explanation:
The volume of a cone has the formula:
[tex]V=\frac{1}{3}\pi r^2 h[/tex]
Where
V is the volume
r is the radius
h is the height
Given,
h = 50
V = 5400π
We want the radius, r.
Lets substitute and solve for r:
[tex]V=\frac{1}{3}\pi r^2 h\\5400\pi=\frac{1}{3}\pi r^2(50)\\5400\pi=\frac{50\pi r^2}{3}\\50\pi r^2=16200\pi\\r^2=324\\r=\sqrt{324}\\r=18[/tex]
The radius is 18 meters
