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
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.
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.
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.
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.
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.
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
