Diameter is half of the radius. Times it by 2.
2.54cm(254mm)
To convert area to diameter for a circle, you can use the formula ( A = \pi r^2 ), where ( A ) is the area and ( r ) is the radius. First, solve for the radius by rearranging the formula: ( r = \sqrt{\frac{A}{\pi}} ). The diameter ( d ) is then found by doubling the radius: ( d = 2r ). Thus, the formula to convert area to diameter is ( d = 2\sqrt{\frac{A}{\pi}} ).
Divide the circumference by Pi (3.1416)

50 diameter to length
To convert diameter to area , you will need to divide the diameter by two so as to get the radius. The result you get, square it and them multiply it by 3.14 to find the area.
Diameter is half of the radius. Times it by 2.
381mm (H) X 254mm (W)
254mm is 25.4cm (divide mm by 10).
