AveGali [126]

Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.

Radius = 4 and height = 8.

Answer:

volume of a cylinder ≈ 402.30  unit cube

Step-by-step explanation:

The question you to find the volume of a cylinder with a height of 8 and radius of 4. The volume of a cylinder can be represented below

volume of a cylinder =  πr²h

where

h = height

r = radius

h = 8

r = 4

volume of a cylinder =  πr²h

volume of a cylinder =  π × 4² × 8

volume of a cylinder =  π × 16 × 8

volume of a cylinder = 128  π

volume of a cylinder =  128 × 3.143

volume of a cylinder = 402.304

volume of a cylinder ≈ 402.30  unit cube
