The cross section at this point forms a circle and its area is pi/32 which equals 9*pi square units. * * * * * Not quite. If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 32) Therefore the cross sectional area is pi*(R2 - 32) square units.
It depends on the cross section which may be circular, elliptical, square, rectangular or of a more complex shape.
If the bar is circular then it is: pi*radius square
The formula for the area of a square is s2 (sides squared)
You need to know the area of that cross-section. Once you have that number, the volume of the box is the product of (cross-section area) x (height).
To calculate the cross-sectional area of a shape, you need to determine the shape of the cross-section first (e.g., square, circle, triangle). Then, use the appropriate formula for that shape. For example, the formula for the cross-sectional area of a square is side length squared, for a circle it is pi times the radius squared, and for a triangle it is base times height divided by 2. Finally, plug in the given dimensions into the formula to calculate the cross-sectional area.

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.
Volume of a cuboid = cross-section area times its length
To find out volume you need to multiply the area of cross-section into its length.
The cross sectional area of a triangular prism is simply the area of the base. The formula for the area of a triangle in one half base times height. Remember that a triangular prism by definition has a triangle for a base.
It is approx 0.003068 square inches.
Usually it means a piece of wood/lumber that has a cross-sectional area of 4 square inches, meaning that the cross section is a square of 2 inch side.
It depends on the cross section which may be circular, elliptical, square, rectangular or of a more complex shape.
The exact answer will depend on what information you have. But generally speaking, Surface area = Perimeter of cross section x Length
The formula for finding the volume for all prisms is area of cross section _ length. Also this formula can be used: length by its width by its height (l _ w _ h).
If the wire has a circular cross-section - the usual case - use the formula for the circle: pi x radius squared.
