Area of a circle = (pi)r2 [Areacircle = pi time the radius squared.]
Volume of a cylinder = (pi)r2h [Volumecylinder = pi times the radius squared times the height.] (This applies to a right circular cylinder. :)
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
volume of cylinder pir2h
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.
The formula for volume of a cylinder is (pi *r2 )h
That depends on what you already know about it. Formulas are just relationships between what you do know and what you don't know. I can't tell you what formula to use until you tell me what you know. Example: If you know the volume of the cylinder and its radius, then Height = Volume / pi xradius2 If you know the area of the cylinder and its radius, then Height = Area / 2 x pi x Radius If you know the volume and area of the cylinder, then Height = Area2 / 4 x pi x Volume
V= AxH where A is the area of the circle, and H is the height of the cylinder.
Finding the volume of a cylinder is similar to finding the volume of a prism because both involve calculating the area of the base and then multiplying it by the height. In a cylinder, the base is a circle, so the formula for the area of a circle (πr²) is used. For a prism, the base can be any polygon, and you multiply the area of that base by the height of the prism. In both cases, the formula is Volume = Base Area × Height.
Volume of a cylinder = pi*radius2*height
Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone
The formula for area of a circle is radius squared times pi. The formula for volume of a cylinder is radius squared times pi times height.
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.
A semi-circle is a 2-dimensional figure and so cannot have a volume.
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone

Finding the volume of a cylinder is similar to finding the volume of a prism because both involve the same basic formula: volume equals the area of the base multiplied by the height. In a cylinder, the base is a circle, while in a prism, the base can be any polygon. Thus, both shapes require calculating the area of the respective base shape before applying the height to determine the total volume. This highlights the fundamental principle of volume calculation across different geometric shapes.
You cannot have a trapezoidal cylinder. That is like a square circle - an impossible shape.
