Area = pi*(diameter/2)2 = pi*252 = 1963.50 mm2
Area = pi*252 = 1963.495 square mm to 3 decimal places
The radius is 1/2 the diameter. In other words, just divide the diameter by 2.
D = 50mm = 5cm Volume of sphere = Pi/6 x D3 = Pi/6 x 125 = 65.45 cubic centimetres (rounded).
It refers to the diameter of the screw. More precisely, it is a 0.138" diameter screw. You can get it in with various head style and thread pitch.
Area cannot be measured in mm. So an area of 50mm cannot exist and therefore, there can be no answer to this question.
Area = pi*(diameter/2)2 = pi*252 = 1963.50 mm2
Area = pi*252 = 1963.495 square mm to 3 decimal places
The volume in liters of a 100mm long by 50mm diameter cylinder is: 0.196 liters.
C = ~157.08 mm
NB = Nominal Bore. Bore is the internal diameter of the pipe. The 50 is referring to 50mm (5cm). So it boils down to a pipe with an internal diameter of 50mm.
The radius is 1/2 the diameter. In other words, just divide the diameter by 2.
Oh, dude, you're hitting me with some geometry now! So, the radius of a circle is half of its diameter, right? That means if the diameter is 50mm, the radius would be 25mm. And if you want to find the diameter from the radius, just double it! Simple math, man.
There are all sorts of screw diameters - major, minor, pitch, mean, etc., but in general a screw diameter is a called by its nominal diameter which is the major diameter of the screw, approximately. For example a 1/2 inch screw has a nominal diameter of 1/2 inch.
area = pi x (502 - 302)/4 = 1256.64 mm2 stress = 80N / 1256.64mm2 = 0.06366 N/mm2
The circumference of a circle is: 2*pi*radius or pi*diameter
The measurements of the lens on the Canon 50mm f1.4 is 2 inches long, and 2.9 inches in diameter. The Canon 50mm f1.4 lens is the most common, useful of Canon lenses.
