The volume of a cylinder is the area of the base (a circle) times
the height of the cylinder. The pipe represents a cylinder.
The area of a circle is PI times the radius squared (PI X r^2)
diameter of pipe = 24 inches implies the radius = 12 inches implies radius = 1 foot. Length of pipe is height of cylinder
new value of PI = 3.1416 exactly (?)
Vol of Cylinder = Area of Base X Height of Cylinder
Vol of Cylinder = Area of Circle X Height of Cylinder
Vol = PI(3.1416) X radius(1 ft.)^2 X height(8 ft.)
Vol = (3.1416 sq.ft.) X height(8 ft.)
Volume = 25.1328 cu.ft. exactly

The formulation for the quantity of a cylinder is V = pi*r^2*h If the diameter is 24 inches, the radius is 12 inches, that's a million foot. V = pi*a million^2*8 V = 8pi V is approximately 25.12 cubic feet in case you utilize 3.14 for pi. the respond is A.

Volume of a cylinder is cross section area time the length. The cross section area is pi times the radius squared which is pi, because the radius is 1 foot and 1 squared is 1. So the volume in cubic feet is pi times 8 or 25.1327412287 cubic feet or 188.00596036 gallons.

volume = pi*(d*2/4)*h
where d is the diameter in feet =24 in/12= 2 ft
and h= length = 8 ft
so volume = pi*(4/4)*8
= 8 pi
or = 25.12 cu.ft

Area x length = pi (1^1) (8) = 25.12 cu ft

Base = 144*pi.
Volume = 8 * 144 * pi.
