Answer:
The ratio of the SA of the big sphere to that a small sphere is 16 : 1
Step-by-step explanation:
Given the radius of the sphere = 24 cm
This sphere is melted to form small spheres of radius of 6 cm
We need to find the ratio of the surface area of the big sphere to that a small sphere.
=
We know that Surface Area = 4 πr²
=>
=>
= 16 : 1
Therefore, the ratio of the surface area of the big sphere to that a small sphere is 16 : 1
