Question

A cylindrical soup can is 10cm tall and had a diameter of 6.36. What is the approximate volume?

Answer 1

V=317.53 
in order to find the volume of a cylinder you use the formula V= (pi) (radius)^2 (height)  
in this problem the diameter was 6.36 but you need the radius so you just divide 6.36 in half and you'll get 3.18 
first you plug in the radius and height into the formula so it'll look like this V= (pi) (3.18)^2 (10) and get the answer which would be 101.12 then you times that by pi which is 3.14 and you will get 317.53 which is your answer
