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.

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!
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 in square mm = pi*1252
Area = pi*282 square mm
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.
Using 3.14 as Pi the area of circle is: 226.865
