a = (pi)r2
1 circular mil = 1 mil x 1 mil a=d2 so if a wire has a diameter of 80 mils, it has an area of 6400 circular mils.
If the bar is circular then it is: pi*radius square
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.
The circular orbit equation used to calculate the motion of objects in a circular path is called the centripetal force equation, which is F mv2/r.
To find the surface area of a prism using pi, you first calculate the area of the base shape, which may involve circular areas if the base is a circle or a shape with circular components. Multiply the base area by the number of bases in the prism (usually two for most prisms). Then, calculate the lateral surface area by finding the perimeter of the base and multiplying it by the height of the prism. Finally, add the base area and lateral surface area to get the total surface area.
The force produced on the circular wall can be calculated using the formula: Force = Pressure x Area. First, calculate the area of the circular wall using the formula for the area of a circle (π x r^2) given the diameter of 3 m (radius = 1.5 m). Then, multiply the pressure of 1100 kPa by the calculated area to find the force exerted on the wall.
It depends on the cross section which may be circular, elliptical, square, rectangular or of a more complex shape.
Assume area of circle= area of squareπd2/4=L2L=0.88263 x dDeduct the cover from L from both sides. This will be length of bar
A good place to measure is the diameter of the circular end. That gives you the area of the circular end, and the only other number you need in order to calculate the cylinder's volume is its straight length.
You calculate 1/3 times the base area s the height. The height should be perpendicular to the base.
The area of Circular Head Council is 4,917 square kilometers.
To find the surface area (SA) of a cylinder, you use the formula: SA = 2πr(h + r), where "r" is the radius of the circular bases, and "h" is the height of the cylinder. The formula comprises the area of the two circular bases (2πr²) and the lateral surface area (2πrh). Simply plug in the values for the radius and height to calculate the total surface area.
