The volume of a cylinder, found using 3.14 to approximate pi, is 50,240 cm3. the radius of the cylinder is 40 cm.
what is the height of the cylinder?
express your answer as a whole number.

V=hpir^2
pi=3.14 for this quesiton
v=50240
r=40
subsitute and solve
50240=h(3.14)(40^2)
50240=h(3.14)(1600)
50240=h(5024)
divide both sides by 5024
10=h

answer is height=10cm

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
