The formula for the volume of a right circular cone, V, is given below, where r represents the radius of the base of the cone an

Mrrafil [7]

Answer:

$r=\sqrt{\frac{3V}{(\pi h)}}$

Step-by-step explanation:

we know that

The volume of a right circular cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of the cone

h is the height

Solve for r-----> That means, isolate the variable r

so

step 1

Multiply by 3 both sides

$3V=\pi r^{2}h$

step 2

Divide by $(\pi h)$ both sides

$\frac{3V}{(\pi h)}=r^{2}$

step 3

take square root boot sides

$r=\sqrt{\frac{3V}{(\pi h)}}$
