Question

Find the volume of the cylinder. Round your answer to the nearest tenth.

Answer 1

Answer:

803.8 cubic centimeters (to the nearest tenth)

Step-by-step explanation:

Volume of a cylinder, V = πr²h

π = 3.14

From the question,

r = radius = diameter/2 = 8cm/2 = 4cm

h = height of the cylinder = 16cm

We substitute these values into the formula

V = πr²h

V = 3.14 X 4²cm² X 16cm

V = 803.8cm³

Therefore, the volume of the cylinder is 803.8 cubic centimeters to the nearest tenth

Answer 2

We know diameter $d=8$ and height $h=16$.

First find the radius of the bottom of the cylinder,

$r=\dfrac{d}{2}=\dfrac{8}{2}=4$.

Then find the area of the bottom of cylinder,

$A=\pi r^2=16\pi$.

Then to find volume just multiply the height with the area of the bottom of the cylinder,

$V=Ah=16\cdot16\pi=16^2\pi\approx804.247\mathrm{cm^3}$.

Hope this helps.
