Question

A solid sphere of radius r is melted and recast into the shape of a solid cone of height r, then the radius of the base of the cone is......

Answer 1

I think this is the right answer
The Radius of the base of the cone
is double the radius of the sphere

Answer 2

Answer:

RADIUS OF CONE = 2r

Step-by-step explanation:

Radius of sphere=r

Volume of sphere=4/3$\pi$r^3

Let radius of the cone be R  

Height of cone=r

Volume of cone=1/3$\pi$r^2h

Volume of sphere=Volume of cone

4/3$\pi$r^3=1/3

4r^3=R^2r

R^2=4r^2

R=2r
