The volume of a cone is 1/3(Area of Base)(height) = 1/3 π r² h
615.44cm³ = 1/3 π 49 h
Divide both sides by (1/3 π 49), and you have your answer.

If the height of the cone is h cm,then
1/3*3.14*7^2*h=615.44
Therefore h
=615.44*3/3.14*49
=12 cm

Let the height be h
r = 7
V = 615.44
We know that,
V = (1/3) * (pi) * (r)^2 * h
Take pi = 3.14
615.44 = (3.14*49h)/3
615.44 = 153.86h/3
153.86h = 615.44*3
153.86h = 1846.32
h = 1846.32/153.86
h = 12
So, the height of the cone is 12 cm
