Question

help ! Find the volume of cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth.( only numerical answers ! )

Answer 1

diameter(d)=8 in.
radius(r)= d/2= 4 in.
height(h)= 3r = 3(4) = 12 in.

Volume=$\pi$r ² h
           =(3.14)(4)²(12)
           =(3.14)(16)(12)
           =602.88 in.
    
       Therefore, the volume of the cylinder is 602.88 in.
