    You will use this formula \[\Large V = \frac{1}{3}\pi*r^2*h\] where r = radius h = height pi is approximately 3.14

    Yes correct \[\Large V = \frac{1}{3}\pi*r^2*h\] \[\Large V = \frac{1}{3}\pi*5^2*11\] \[\Large V = \frac{1}{3}\pi*25*11\] Do you see how to finish up?

    25 times 11 = 275 then you multiply 275 by 1/3 to get ???

    now multiply that with the value of pi, which is approx 3.14

    turns out that \[\Large 91.\bar{6} = 91 \frac{2}{3}\]

    so \[\Large V = \frac{1}{3}\pi*25*11\] \[\Large V = 91.\bar{6}\pi\] \[\Large V = 91 \frac{2}{3}\pi \]

    Another way to get 91 & 2/3 is to do 275/3 = 91 remainder 2 The 91 is the quotient The remainder of 2 forms the numerator over 3
