Answer with Step-by-step explanation:
V=kr²h
Where r is the radius and h is the height of the cylinder
Cylinder A has a volume of 251.2 cubic inches and has a radius of 4 inches and a height of 5 inches.
⇒ 251.2=k×4²×5
⇒ 251.2=80k
⇒k=251.2/80
⇒ k=3.14
We have to find volume of cylinder B, which has a radius of 3 inches and a height of 9 inches
r=3 inches
h=9 inches
V=3.14×3²×9
=254.34 cubic inches
Hence, Volume of cylinder B is:
254.34 cubic inches
