Answer:
The correct answer for this question is Option C. 20
Let the height of the cone be h cm
4/3 πr³ = 1/3πr³h
4r = h
4 x 5 = h
h = 20 cm

Given:
Sphere,
Radius = 5 cm
To find:
The height of the cone
Solution:
The sphere is melted to form a cone.
Hence, Volume of the sphere = Volume of the cone
4 / 3 * π * ( radius )^3 = 1 / 3 * π * ( radius )^2 * height
Cancelling all the common terms,
4 * radius = height
Substituting,
4 x 5 = h
Hence, Height = 20 cm
