WebThe formula for the volume of a cylinder is: V = Π x r^2 x h "Volume equals pi times radius squared times height." Now you can solve for the radius: V = Π x r^2 x h <-- Divide both sides by Π x h to get: V / (Π x h) = r^2 <-- Square root both sides to get: sqrt (V / Π x h) = r 3 comments ( 21 votes) Show more... macy hudgins 4 years ago WebTom Rocks Maths intern Isaac Wood introduces the most amazing formula for pi - involving prime numbers and multiples of 4 - and shows you how to prove it.The...
