24501.42 "units"^3

Explanation:

The volume of a cylinder is given by

πr^2h

with r as the radius, and h as the height.

Here π is 3.14 as stated in the question. Identify the radius and height:

r=17

h=27

Plug into the formula:

3.14*17^2*27=24501.42

The answer is 24501.42 "units"^3.

24,513.84 m^3

Explanation:

If we know the diameter of the cylinder is 34m, we divide by 2 to get the radius.

34/2 is 17, so our radius is 17.

The formula to find the area of a circle is πr^2.

17^2 is 289. 289 xx π is approximately 907.92.

We know the height of the cylinder is 27m, so we multiply the area of the circle by the height (907.92 xx 27), giving us 24,513.84 m^3.

V="24501.42 m"^3"

Explanation:

The formula for the volume of a cylinder is:

V=pir^2h,

where pi is 3.14 (according to the diagram), r is the radius (1/2 diameter), and h is the height.

The diagram shows the diameter of the top and bottom of the cylinder. The radius is half the diameter:

r=1/2d

r=1/2(34"m")="17 m"

The height (h) of the cylinder is "27 m".

Plug the known values into the equation and solve for volume.

V=(3.14)(17"m")^2(27"m")

V=(3.14)(289"m"^2)(27"m")

V="24501.42 m"^3"
