The second one is the answer.
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
Answers
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
How do you solve this?
Factor.
