The formula to calculate cross sectional area of a cylinder is pi (a constant value, approximately 3.14) multiplied by the radius of the cylinder (half the diameter, so half the distance from on side of the circle to the other) squared (multiplied again by itself) So if the circular end of the cylinder is 10 centimeters across, then the diameter is 10cm and the radius is 5cm. The cross sectional area would be calculated as: 3.14 x 5cm x 5cm = 78.5cm squared.
Volume of a cylinder = (area of its cross-section) x (its length) If the end is a circle, then the area of the cross-section = (pi) x (half the diameter)2 = (pi) x (radius)2 Then Volume = pi R2 L
By definition, a cylinder has two equal circular (or elliptical) faces and a uniform cross section. Therefore, a cylinder cannot be tapered.
by math
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.
Simply work out the area of a section of cable.........
You compute the area of the cross section (a circle), then multiply the result with the cylinder's height.
Lol at your life
If the steel rod has a circular cross-section - the usual case - you can use the formula for a cylinder. Since the area of the base is quite small, it can be ignored - just calculate length x diameter x pi.
= area of a circle = pi*r^2 or length x width if the cross section is longitudinal (since the area will be rectangular)
You cannot unless you know the angle of the plane which defines the cross section.
Volume of prism = area of cross section x length.
Its volume is: cross-section area times its length
