The diameter of the football is 5 times the diameter of the cricket ball. This means that the radius of the football is also 5 times the radius of the cricket ball.
Let the radius of the football be R.
Let the radius of the cricket ball be r.
This implies that:
R = 5r
Both balls are spherical.
The surface area of the cricket ball is given as:
The surface area of the football is given as:
Therefore, the ratio of their surface areas is:
A : a
= 100 : 4
25 : 1
