An air-filled rubber ball has a diameter of 6 in. If the air pressure within the ball is increased until the diameter becomes 7
Yakvenalex [24]

we are given

An air-filled rubber ball

d_0=6in

d=7in

we can use formula of the average normal strain in the rubber

\delta =\frac{\pi d - \pi d_0}{\pi d_0}

now, we can plug values

and we get

\delta =\frac{\pi*7 - \pi*6}{\pi* 6}

\delta =0.16667in/in...........Answer
