Best Answer

Area is pi times the radius, squared.

And circles are two-dimensional. There is no volume. But for cylinders, the area is pi times the radius squared, times two, times the height.

A circle is two dimensional, it has area but not volume.

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

Circles don't have volume, but they do have area.

A semi-circle is a two dimensional figure so it can have area but NOT volume. To find the area of a semi-circle see the question below.

There is none because a circle has no volume but the area of a circle is pi*radius^2

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.

A circle has no volume. Volume is only for 3-D shapes. A circle does not have volume because it is a 2 dimentional figure.A circle can only have circumfrance and area. Only a 3 dimentional figure can have volume. Mabye you are thinking about a sphere.

Volume= Base(Height) Base= Area of the Circle. Area of a Circle= π r^2 (pi times radius squared)

The area of a circle is 'pi' multiplied by the square of the circle's radius.The volume of a circle is zero. As a circle has only two dimensions.The volume of a sphere is (4/3 pi) multiplied by the cube of the sphere's radius.

Because the volume of the cylinder is proportional to the cross sectional area of the cylinder. The cross sectional area is a circle and the area of a circle is pi*r2.

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 ?

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.
