Question

The area of the outer surface of a very thin outer coated football in 100Πcm^2 what is the volume of air inside the football?​

Answer 1

Answer:

523.81(approx)

Step-by-step explanation:

Given ,

CSA=4pi r^2 sqcm = 100 pi sqcm

r = root(100 pi/4 pi)

=5

Volume = 4/3pi r^3

=4/3 x pi x 5^3

=4/3 x pi x 125

=4/3 x 22/7 x 125

= 523.809

= 523.81(approx)
