The answer is B. h=<span>V<span>2π<span>r<span>2</span></span></span></span>
I think as in whole numbers in numerator it should be in improper fraction since 4.5= 4wholes and 5/10 it's 9/2?
and 2.5 in mixed fraction is 2 wholes 5/10 in improper is 5/2
unless you say mixed fraction is okay to leave if for the answer than it's respectively 4wholes 1/2 and 2wholes 1/2?
I'm not sure but I learnt this in my school and it goes like this
