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.

How do you find the volume of circle?

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


What si the formula to find the volume of a circle?

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


HOW TO find the volume of a circle?

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.


How do you a measure the volume of a circle?

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.


Why do you square the radius when finding the volume of a cylinder?

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.


How do you find a radius of a cylinder if you only have a volume and area of base?

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 ?


How are the formulas for the area of a circle and the volume of a cylinder related?

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.


What is the Volume formulae of a semi-circle?

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.


How does the formula of the area of a circle relate to the volume of a cylinder?

The volume of a cylinder is its height times the area of its base. And the area of its base is the area of a circular shape.


Volume of a circle?

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.


What is the volume of cylinderical tank the Height is 246 cm radius is 39 cm.?

Solving this is pretty straightforward. You simply find the area of the circle and multiply that by the height of the cylinder. Area of Circle = Pi * (Radius ^2) Note: "^" means raise to the power of So: Area of Circle = 3.14159 * (39^2) Area of Circle = 3.14159 * 1521 Area of Circle = 4778.362426 cm^2 Now multiply area of circle by height of cylinder: Volume = 4778.362426 * 246 Volume = 1,175,477.157 cubic cm Answer: 1,175,477.157 cubic cm
