Question

If the height and radius of a cone are doubled. Find the volume of cone how many times increase​

Answer 1

Step-by-step explanation:

The new volume (Vn) of the cone on doubling the radius and height = (1/3)(pi)(2r)^2(2h) = 8[(1/3)(pi)(r^2)h}. The volume of the cone becomes 8-fold if the radius and height of a cone are doubled. Or it will increase by 700%.
