The diameter of a cylindrical construction pipe is 5 ft. if the pipe is 21 ft long, what is its volume?
use the value 3.14 for 7, and round your answer to the nearest whole number.
be sure to include the correct unit in your answer

Volume of Construction Pipe is .

Step-by-step explanation:

A Construction pipe is cylindrical in shape.

Height  (h) = 21 ft.

Diameter (d) = 5 ft.

We need to find the Volume of Construction pipe.

We will first find the radius.

Radius can be given as half of diameter.

hence Radius (r) =

Since Construction pipe is in Cylindrical Shape we will find the volume of cylinder.

Now We know that Volume of cylinder can be calculate by multiplying π with square of the radius and height.

Volume of Cylinder =

Rounding to nearest whole number we get;

Hence,Volume of Construction Pipe is .

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
