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.
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.
= area of a circle = pi*r^2 or length x width if the cross section is longitudinal (since the area will be rectangular)
Volume of prism = area of cross section x length.
To calculate Cross Sectional Area: Width x Depth
Consider it as cylinder..
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.
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 area of a cross section of a cylinder that is parallel to its base is equal to the area of the base. In this case, the base of the cylinder is a circle with a radius of 8 inches. Therefore, the area of the cross section is 64pi square inches.
Simply work out the area of a section of cable.........
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.
Lol at your life

just not to confuse you, here is the question more clearer: A prism has a cross section that is a regular hexagon The area of the cross section is 10.4m^2. The volume of the prism is 8.84m^2. Calculate the height of the prism.
Volume = Length*Area of cross-section So area of cross section = 1962.5/25 = 78.5 units If the cylinder has diameter d then area of cross section = pi*d2/4 So d2 = 4*Area/pi = 99.95 square units. Then d = sqrt(99.95) = 9.997 units of length.
You cannot unless you know the angle of the plane which defines the cross section.
Volume of prism = area of cross section x length.
