Write the formulawith the giveninformationand solvefor.Volumeof a RightCylinder
You haveseenhow to find the volumeof any right prism.
where is the area of the prism’s baseand is the heightof the prism.
As you mightguess,right prismsand right cylindersare very similarwith respectto volume.In a sense,a
cylinderis just a “prismwith roundbases.”One way to developa formulafor the volumeof a cylinderis to
compareit to a prism.Supposeyou dividedthe prismaboveinto slicesthat were unit thick.
