It is not possible to give an exact value since the calculation involve π. Since π is an irrational number, there is no exact representation for it.
What do you mean by "exact measurement"? Do you wish to determine the cylinder's height? Its diameter? Its surface area? Its volume?
The height of a sphere is the same as its diameter, and the formula for volume of a sphere is (4/3) x pi X radius cubed. The radius is half the diameter, and in this instance the formula yields about 113.0973355 cubic inches if the value 6 is considered exact, otherwise 1.1 X 102 cubic centimeters to the justified number of significant digits.The formula for calculating the volume of a sphere is: Volume 4/3 * π * r3. Note that the given height of the sphere 6cm is equal to the diameter of the sphere. The formula requires a radius or half the diameter. Therefore, the Volume 4/3 * 3.14 * (3 * 3 * 3 or 27) = 113.0399 or 113.04 cubic centimeters.Note that the given unit of measurement is in centimeters. You cannot just change the unit of measurement to inches and back to centimeters. The above calculation is also a few hundredths off.
1000 cubic centimeters is a measure of volume; the only "exact equivalant in volume" possible would be in another measure of volume, such as cubic inches, cubic feet, cubic meters, etc.
I am not sure what you mean by "Use pi for p?", but anyway, the volume of a cylinder is calculated by first calculating the area of the base (the circle), then multiplying this result by the height. Also, an "exact" answer is not possible since the result for pi is an irrational number that goes on indefinitely. Having said that, a practicle answer is 226.285714285714285714 cm3 (the .285714 repeating ad infinitum). I arrived at this result using 22/7 as the value of pi, rather than 3.14.......
A formula for the volume of a cylinder is 2 X pi X r2 X h, where r is the radius and h is the height. This formula yields about 3053.628059 cubic centimeters if the integers specified are considered exact or 3.1 X 103 cubic centimeters to the justified number of significant digits otherwise.
Exact is difficult but it is approximately 2.713 cc.
A half-inch diameter would be approximately 1.27 centimeters in the metric system.
(circumference=2πr or πd) so the circumference in exact form would be π726.4
Priyanka Chopra has got a nice figure. Her height is also very good. Her exact height is 171 cm if taken in centimeters.
The volume of peanut butter would depend on the container it is in. To find the volume, you would measure the length, width, and height of the container holding the peanut butter and calculate the volume using the formula volume = length x width x height. The volume measurement would be in cubic units (such as cubic centimeters or cubic inches).
The volume V of a cylinder with diameter d and height h = pi X (d/2)2 X h. Substituting the known values into this formula yields pi X 1.52 X h = 45, or h = 45/(pi X 1.52) = 6 feet, to the justified number of significant digits, or if the integers specified are considered exact, 6.366197724 feet.
Volume of cylinder: pi*2.2^2 *4.9 = 75.50601137 cubic yards
