area=pi r squared
the r is the radius which is half of the diameter
so area =pi mulitplied by 45 squared
which is 6361.725124mm
The area of a circle whose diameter is 6 mm is: 28.27 mm2
A circle with a radius of 50 mm has an area of 7853.98 square mm
Area in square mm = pi*1252
Diameter of circle: 70/pi = 22.28 mm rounded to two decimal places
Oh, dude, you just gotta divide the diameter by 2 to get the radius, which is 120 mm. Then you square that bad boy to get 14,400 mm². So, like, the area of the circle is 14,400 mm². Easy peasy, lemon squeezy.

I do not know about a circle with an area of 100 nmm3.A circle with an area of 100 mm2 has a diameter of 11.28 mm.
A circle with a diameter of 25 mm has an area of 490.9 square mm.
Area = pi*282 square mm
Area in square mm = pi*1252
Area = pi*552 square mm
Diameter of circle: 70/pi = 22.28 mm rounded to two decimal places
A circle with a diameter of 4 mm has an area of : 12.57 mm2
Oh, dude, you just gotta divide the diameter by 2 to get the radius, which is 120 mm. Then you square that bad boy to get 14,400 mm². So, like, the area of the circle is 14,400 mm². Easy peasy, lemon squeezy.
Well, honey, if the diameter of a circle is 7 mm, then the radius is half of that, which is 3.5 mm. The formula for the area of a circle is πr^2, so plug in 3.5 for the radius and you get an area of approximately 38.48 square millimeters. So there you have it, darling!
Using 3.14 as Pi the area of circle is: 226.865
