Answer:
Given:
To find: Radius of the sphere
Proof:
According to the question,
(When melted, the volume remains constant)
Let the radius of the sphere= R cm
Therefore,
is common, we'll cut from both the sides]
Substituting the values in the equation, we get:
Hence, the radius of the solid sphere =
R= 5 cm.
