A=22/7x8mm squared
The formula, when the radius is known, is: A = PI(r)2 A circle with a radius of 450 mm has an area of 636,172.51 square mm.
The square root of (4298.66/pi) = 36.9906201 or a radius of 37 mm
Just like any other circle, the area of that one is (pi) times (the square of the radius).
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.
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 radius of a circle with an area of 35 mm squared is 3.34mm
27.2 mm
The area and circumference of a circle with a radius of 9.5 mm are:A = 284mm2C = 59.7mm
A circle with a radius of 50 mm has an area of 7853.98 square mm
The formula, when the radius is known, is: A = PI(r)2 A circle with a radius of 450 mm has an area of 636,172.51 square mm.
The area of a circle whose diameter is 6 mm is: 28.27 mm2
~12.56
The square root of (4298.66/pi) = 36.9906201 or a radius of 37 mm
50.265 square mm
If radius = 45 mm, then area = 6361.7 mm2 (to 1 dp).
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!
Just like any other circle, the area of that one is (pi) times (the square of the radius).
