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).
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.
