Answer :

Let the Radius of cone be ‘r’ and height of cone be ‘h’

r = 21 cm and h = 84 cm

Explanation: Here the volume of cone will be equal to the volume of the resulting sphere as the resulting sphere is formed by melting the cone.

Volume of cone,  V1 = π × 441 × 28

V1 = 12348π m3eqn1

Let the Radius of resulting sphere be ‘R’ cm

Volume of the sphere= Now equate equation 1 and 2,

V2 = V1   R3 = 3087 × 3

R3 = 9261

R =(9261)

R = 21 cm

Diameter of Sphere = 2 × radius

Diameter of Sphere = 2 × R = 42 m

Diameter of the resulting Sphere is 42 m
