Question

A solid right circular cone or radius 4 cm and height 7 cm is melted to form a sphere. Find

the radius of sphere

Answer 1

Answer:

Step-by-step explanation:let the radius of cone be R and height h

And radius of sphere be L

According to question,

1/3 π *Rsquare*h=4/3π*Lcube

3 and π got cut

We get ,*Rsquare*h=4*Lcube

Using the given information,

4*4*7=4 *Lcube

4 cut by 4

We get L cube = 28

L=√28=5.29cm
