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.
Answer:
Volume of sphere is
Step-by-step explanation:
It is given that Hal says that volume of sphere is
Volume of sphere is given by
Now using 3.14 in place of
Now volume of sphere is
Therefore volume of sphere when we use 3.14 in place of is
And the Hal likely error is he uses directly for calculation of volume.
