The radius is 1/2 the diameter. In other words, just divide the diameter by 2.
Area = pi*(diameter/2)2 = pi*252 = 1963.50 mm2
D = 50mm = 5cm Volume of sphere = Pi/6 x D3 = Pi/6 x 125 = 65.45 cubic centimetres (rounded).
Area = pi*252 = 1963.495 square mm to 3 decimal places
It is a diameter of 39.37 cm.
The volume in liters of a 100mm long by 50mm diameter cylinder is: 0.196 liters.
C = ~157.08 mm
Area cannot be measured in mm. So an area of 50mm cannot exist and therefore, there can be no answer to this question.
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.
quite big, maybe
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.
Area = pi*(diameter/2)2 = pi*252 = 1963.50 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.
50mm = 50 x 10^-3 m = 50 x 0.001 m = 0.05m or 5cm.
50mm is 0.164 foot.
