Question

The formula for the volume of a come is V=1/3πr^2h. The radius, r, of the cone may be expressed as

Answer 1

                                   Volume = (1/3) (π) (r²) (h)

Multiply each side by 3:    3V = (π) (r²) (h)

Divide each side by π :    3V/π = (r²) (h)

Divide each side by h :      3V / πh = r²

Take the square root
of each side:                      r  =  √ (3V/πh)  .
