Not quite sure what you mean by "volume". Pi is an irrational number, meaning that it can't be written exactly as a decimal, or as a fraction. However, you can get as close as you like, by writing sufficient decimals. The 12 or 15 digits provided by calculators and computers are usually more than enough.

Exact value of pi to 10 decimal places?
3.1415926536 is to 10 places but not exact. The only exact value of pi is pi itself. So any exact answer involving pi would include pi in the answer.
How do you find the radius of a cylinder using volume and height?
Volume = pi x r^2, so r^2 = volume/ pi r = sq root(volume/pi).
How much water does it take to fill a twenty four inch pipe by one foot long?
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
How do you find the volume for circular cylinder?
Volume = (Pi/4) * diameter2 * height or volume = Pi * radius2 * height
What is the exact area of a circle with a diameter of 25 m?
The exact area is 625*pi. Since pi is an irrational number, any exact answer must include pi and may not contain a decimal (or rational) approximation of pi.
What is the exact area and volume of a sphere with radius 6?
Area: 4*pi*6 squared = 144*pi square units Volume: 4/3*pi*6 cubed = 288*pi cubic units
Who found out how th calculate the volume of a sphere?
No one because the volume of a sphere is 4/3*pi*radius cubed but it is only an estimation because the exact value of pi has never been found.
Exact value of pi to 10 decimal places?
3.1415926536 is to 10 places but not exact. The only exact value of pi is pi itself. So any exact answer involving pi would include pi in the answer.
What is the exact volume of a cylinder that has a height of 4.9 yd and a radius of 2.2 yd?
Volume of cylinder: pi*2.2^2 *4.9 = 75.50601137 cubic yards
The volume of a right circular cylinder can be approximated as follows Volume and pir2h where r is the radius of the cylinder and h is the height of the cylinder and pi is a constant that is roughly e?
First, it is not an approximation but the formula for the exact value of the volume. Second, pi and e are quite different numbers.
How do you find the height of a can if the radius is 4cm and it is a 400mL can in the shape of a cylinder with an exact answer?
Volume of a cylinder = {pi}r2h. 1 litre = 1000cm3 so 1ml = 1cm3, thus 400ml = 400cm3 400cm3 = {pi}(4cm)2h h = 400cm3/({pi}16cm2) h = 25/{pi} cm As an exact answer is required, leave it in this form instead of dividing through (to get about 7.96cm).
How do you find the radius of a cylinder using volume and height?
Volume = pi x r^2, so r^2 = volume/ pi r = sq root(volume/pi).
How much water does it take to fill a twenty four inch pipe by one foot long?
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
How do you find the volume for circular cylinder?
Volume = (Pi/4) * diameter2 * height or volume = Pi * radius2 * height
What is the exact area of a circle with a diameter of 25 m?
The exact area is 625*pi. Since pi is an irrational number, any exact answer must include pi and may not contain a decimal (or rational) approximation of pi.
What is the exact history of mathematical pi?
The circumference of any circle when divided by its diameter has the exact value of pi
What is the volume of a sphere with a radius of 15cm?
Volume = 4/3*pi*153 Volume = 4500*pi cubic cm
