Question

A SPHERE OF RADIUS 8CM IS MELTED AND RECASTED INTO SPHERE OF 1 CM. HOW MANY SUCH SPHERE OF 1CM RADIUS CAN BE MADE?

Answer 1

Answer:

512 spheres

Step-by-step explanation:

Volume of circle with the larger radius = 4πr^3 = 4π×8×8×8 = 2048πcm^3

Volume of circle with the smaller radius = 4π^3 = 4π×1×1×1 = 4πcm^3

Number of such spheres can be made = 2048π/4π = 512 spheres
