Answer:
213.52 cubic ft
Step-by-step explanation:
Diameter of pipe = 4ft
radius for circle is half of diameter
thus radius of pipe = 1/2 of 4ft = 2 ft
length of pipe = 17 feet
volume of cylinder is given by
where r is the radius and l is the length of cylinder
.
thus volume of pipe is calculated below using above values
volume of pipe is 213.52 cubic ft.
