Area of a circle = pi*r2 , where pi = 3.14 and r is the radius of the circle.
We have diameter(d) = 12mm so, radius(r) = d/2 = 6mm
On putting the values we get
Area = 3.14*62 = 3.14*36 = 113mm2
The radius of a circle is always half of the distance of the diameter. If you have a 24 mm diameter - then the radius would be 12 mm.
A circle with a diameter of 25 mm has an area of 490.9 square mm.
Area = pi*282 square mm
Area = pi*552 square mm
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
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
The radius of a circle is always half of the distance of the diameter. If you have a 24 mm diameter - then the radius would be 12 mm.
24 mm. The diameter is twice the radius.
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
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!
