A circle with a radius of 50 mm has an area of 7853.98 square mm
Diameter of a circle is pi times the square of its radius. For a circle having a diameter of 7 mm, area = pi (3.1416) x 3.5 mm x 3.5 mm = 38.5 square millimeters.
Area in square mm = pi*1252
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.
Area = pi*502 in square mm
346.36 square MM.
Area = pi*24.52 square mm
