A frustum of a cone is that part of the surface of a cone between two planes perpendicular to the axis of the cone; if a cone has base radii r1 and r2 and slant height h, then its area, A is given by
A = 2*pi*h*(r1+r2)/2

Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
What happens to the cross-sectional area of metal wire if you double the diameter?
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
How does the cross sectional area of wire affect resistance?
Other things being equal, more cross-sectional area will cause less resistance.
Why do you square the radius when finding the volume of a cylinder?
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.
Which has the greatest cross sectional area?
9 AWG
What is the meaning of Cross sectional area in a river?
Cross Sectional Area = Width x Average Depth
What is an Initial average cross-sectional area?
the average of the projected surface areas
How do you do a cross sectional area of a rectangle?
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
How does cross sectional area affect resistance?
the larger the cross sectional area, the smaller the resistance
How do you calculate cross sectional area?
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.
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
Cross sectional area of concrete slab?
The cross sectional area of a slab can be found by squaring the height of the slab.
What is average velocity of water in pipe?
The average velocity of water in a pipe depends on the flow rate of the water and the cross-sectional area of the pipe. It can be calculated by dividing the flow rate by the cross-sectional area. The units are typically expressed in meters per second.
How do you work out the cross sectional area of a trapezoidal prism?
cross-sectional area = 0.5*(sum of parallel sides)*height
How do you calculate forging reduction ratio?
reduction ratio= initial cross sectional area/final cross sectional area
What is the cross sectional area of a y12 bar?
A Y12 bar typically has a cross-sectional area of 113 square millimeters.
How do you find cross sectional area of cable when you have the lent current and the voltage drop?
cross sectional area of cable * voltage drop
