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.
That's 50mm. 2X2.5cm=5cm=50mm
You can make your circle as large or as small as you want.
quite big, maybe
The circumference of a circle is: 2*pi*radius or pi*diameter
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.
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.
Area = pi*(diameter/2)2 = pi*252 = 1963.50 mm2
Area = pi*252 = 1963.495 square mm to 3 decimal places
It is: 50mm = 5cm
The radius is 1/2 the diameter. In other words, just divide the diameter by 2.
Canon makes the best 50mm camera lens, known as the EF 50mm f/1.8mk2, 50mm f/1.4 USM and 50mm f/1.2L lenses
50mm from 0.14mm = -49.86mm
50mm converts to 0.05m (multiply millimeters by 0.001)
