Circles do not have volume because they are 2 dimensional. The area of a circle is PI*r2 . A sphere has volume and the volume of a sphere is 4/3*pi*r3 where r is the radius.
A circle is two dimensional, it has area but not volume.
4/3[pie]rcube
you calculate the Area of the circle at the end of the Cylinder and then multiply it by the lenght to the second circle at the end of the cylinder Circle area= Radius*Radius* pi pi being 3.14159265
With great difficulty because a circle is a 2 dimensional shape that has no volume or may be you meant a sphere which is: Volume of a sphere = 4/3*pi*radius3 Area of a circle = pi*radius2
Calculate the base area using the formula for a circle. The calculate the volume with the formula: V = (1/3)Bh
Divide the volume by the hieght. The result is the area of the circle forming the cylinder. Divide the area of the circle by PI. Multiply by 4 and then take the square-root. This will be the diameter of cylinder.
I think you are asking how do you calculate the VOLUME of a disk 250mm with a thickness of 20 mm. If that is so, then find the area of the circle using the Area = pi times radius squared formula and then multiply by the thickness to get cubic millimeters volume.
It is used to calculate the circumference and the area of a circle, the surface area and volume of a sphere, to calculate areas and volumes of some other geometrical figures, and in several applications in advanced math that are seemingly unrelated to the circle.
When you calculate the volume of pipe(or cylinder, as I prefer calling it), you need to know 2 things; the height of the cylinder and the radius of the circle(base of the cylinder). Then you use this formula; hpr^2 (height * pi * radius)
circle does not have volume
For several calculations related to circles and spheres - relation between the circumference and the radious of a circle, calculate a circle's area, calculate the volume or the surface of a sphere. Also in several integrations (calculation of areas), which seem to be unrelated to circles, and in statistics - also in contexts where the relationship to a circle is not obvious.
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
