A circle is a two-dimensional object. Two-dimensional objects do not have volumes. Perhaps you were thinking of a sphere?
There is no volume in a circle but volume can be found in a sphere. The question should be rephrased. A circle is a two dimensional shape, so it cannot have a volume which is a characteristic of a three dimensional shape.
A circle does not have volume since it is a 2 dimensional shape. Volume requires 3 dimensions.
pi r^2 h is used to determine the volume of a cylinder because when determing the area of a shape you first have to determine the area of the the base of the object and then multiply it by the height. The base of a cylinder is a circle and to find the area of a circle you use pi r^2 and hence the reason why pi r^2 is used to find the volume of the cylinder.
The volume of a cylinder is the cross-sectional area of the cylinder multiplied by its length. The perpendicular cross-section of a cylinder is a circle.
circle does not have volume
There is none because a circle has no volume but the area of a circle is pi*radius^2
circumference is the perimeter of a circle. a circle is 2 dimensional. volume is 3 dimensional. you need to state what shape it is. I could guess that you are talking about a cylinder. the volume is pi.r2.h, if you find the radius from the volume, you can find the perimeter of the circle by 2.pi.r
The area of a circle is 'pi' multiplied by the square of the circle's radius.The volume of a circle is zero.The volume of a sphere is (4/3 pi) multiplied by the cube of the sphere's radius.
With great difficulty because a circle does not have volume but it does have an area. Area of a circle = pi*radius2 and measured in square units
This question cannot be answered sensibly since a circle cannot have a volume.
A circle has no volume. It is a planar figure and is flat, and it has no thickness. A circle does not have any thinkness just as a plane, the construct on which it is drawn, has no thickness.
A circle has neither mass not volume so its density is not defined.
Hemisphere volume = [(4 / 3) πr3] / 2
If you have area of base, then who needs the volume ? The whole problem is nothing but a circle question. The base is a circle. The area of a circle is (pi R2), and you know the area. Do you think you can find 'R' now ?
Technically, a circle is a 2-dimensional object, so the question should read "volume of a sphere" OR "Area of a circle". The formula to work out the volume of a sphere is: 4/3 pi x r3, where "r" is the radius of the sphere. To find the area of a circle: pi x r2.
Wouldn't a circle-based pyramid look a lot like a cone ? If so, you could probably use the formula for the volume of a cone and get away with it.
