The formula is 4/3 times pi (π) times the radius cubed.
Radius is 1/2 the diameter. Diameter is 2 so radius is one.

A 2-inch diameter sphere has a volume of 4.189 cubic inchesA 1-inch diameter sphere has a volume of 0.5236 cubic inches.
Assuming cylinder: volume = area of circle * length area of circle = pi*radius**2 radius = circumference/(2*pi) radius = diameter/2 if 24 inch is circumference: volume = pi*(24/(2*pi))**2 * 12 volume = 144/pi*12 volume = 1728/pi inch**3 if 24 inch is diameter: volume = pi*(24/2)**2 * 12 volume = pi*144*12 volume = pi*1728 inch**3 if 24 inch is radius: volume = pi*24**2 * 12 volume = pi*576*12 volume = pi*6912 inch**3 if 24 in
Assuming that 0.75 inch refers to the diameter, the volume is pi*(0.75/2)2*12 = 5.3 cubic inches, approx.
The volume of a sphere is 4/3*pi*r3 where r, the radius = 3/2 = 1.5 inches3. = 14.137 cubic inches.
-- Measure the diameter of the ball (the fattest dimension).-- Take the "cube" of that number. (itself x itself x itself)-- Multiply the result by 0.5236The answer is the volume of the ball in cubic-(same unit as the diameter of the ball).Note: Where the 0.5236 came from ... it's (4/3 pi) x (1/2)3
A 2-inch diameter sphere has a volume of 4.189 cubic inchesA 1-inch diameter sphere has a volume of 0.5236 cubic inches.
Divide the diameter by 2 to get the radius. Then use the formula for the volume of a sphere.
If the flow velocity remains the same the flow volume will increase by the square of the diameter ratio.(2/1.25) = 1.6 = diameter ratio1.62 = 2.56 more flow volume through 2 inch pipe compared to 1.25 inch pipe.
1.15 gallons of water.
volume = pi r squared multiplied by the length you didnt specify wether 2 inch pipe was diameter or radius
Assuming cylinder: volume = area of circle * length area of circle = pi*radius**2 radius = circumference/(2*pi) radius = diameter/2 if 24 inch is circumference: volume = pi*(24/(2*pi))**2 * 12 volume = 144/pi*12 volume = 1728/pi inch**3 if 24 inch is diameter: volume = pi*(24/2)**2 * 12 volume = pi*144*12 volume = pi*1728 inch**3 if 24 inch is radius: volume = pi*24**2 * 12 volume = pi*576*12 volume = pi*6912 inch**3 if 24 in
Assuming that 0.75 inch refers to the diameter, the volume is pi*(0.75/2)2*12 = 5.3 cubic inches, approx.
The volume of a sphere is 4/3*pi*r3 where r, the radius = 3/2 = 1.5 inches3. = 14.137 cubic inches.
The volume of the ball, right? You can measure the ball's diameter, divide by 2 to get the radius, then use the formula for the volume of a sphere. If you find it difficult to measure the diameter, you can also measure the circunference, and divide that by (2 x pi) to get the radius.
Circumference of pool ball: 2*pi = 6.283 inches rounded to 3 decimal places
If that is the radius, use the formula: volume = (4/3) pi r3. If that is the diameter, divide it by 2 first, to get the radius.
Volume of a sphere = 4/3 (pi) (radius)3Radius = 1/2 diameterVolume of a 3-inch-diameter ball = 4/3 (pi) (1.5)3 = 4.5 (pi) cubic inchesYou should have no trouble taking care of the (pi) factor and rounding theresult any way you want it.
