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).
Calculate cross sectional area of wire?
If the wire has a circular cross-section - the usual case - use the formula for the circle: pi x radius squared.
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.
What is the formula of cross sectional area for a coin?
The formula for the cross-sectional area of a coin is calculated using the formula for the area of a circle, which is A = πr^2. In this formula, A represents the area, π is a constant approximately equal to 3.14159, and r is the radius of the coin. By substituting the radius of the coin into the formula, you can calculate the cross-sectional area of the coin.
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.
What is the cross sectional area of a two liter bottle?
To derive the cross sectional area of a two liter bottle do the following formula. Area = (radius * 2.54 cm/in)^2 * pi = X cm^2.
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
What is the formula of Cross-sectional area of hexagon?
3*sqrt(3)/2*r^2
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
What is formula of resistivity?
R is the electrical resistance,A is the cross-sectional area,l is the length of the piece of material.
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 the meaning of Cross sectional area in a river?
Cross Sectional Area = Width x Average Depth
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
