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.
If the diameter of a circle is 50 mm, what is the radius?
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
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.
