Question

Carl knows the required height of the volume of a cone-shaped vase he’s designing. Which formula can he use to determine the radius of the vase. Select the correct answer.

A. r = V/ 3πh
B. r = V /πh
C. r = 3V/ πh
D. r = ± /V πh

Answer 1

the volume of a cone is calculated like this:
V = pi*r^2*h/3
so we have to solve for radius:
r = √(3V/pi*h)
that is how to get the radius.
From your answers, C answer approaches to it, but it lacks the square root which is fundamental as well
