Answer:
See below
Step-by-step explanation:
We want to prove that

Taking the RHS, note

Remember that

Therefore,

Once

Then,

Hence, it is proved
So 4 inches diameter result the radius is 4/2 = 2 inches
area of base = pir^2 = 3,14*2^2 = 3,14*4 = 12,56 inches squared
volume = area of base *height
V = 12,56 *9 = 113,04 so rounded 113,05 inches cubed
hope this will help you
