It is 8.5 mm, of course!
A circle with a radius of 6 mm has a circumference of 37.7 mm
Radius of the circle: 6.28/2*pi = 0.999 mm or about 1 mm
Oh, dude, you're hitting me with some math here. So, the circumference of a circle is calculated by multiplying the diameter by pi (π). Since the diameter of a circle is twice the radius, and you've given me the radius (40 mm), I can tell you that the circumference of a 40 mm circle would be approximately 251.2 mm. It's like math, but with a side of sarcasm.
To determine the roundness of a circle, we typically calculate its circumference divided by its diameter. In this case, for a 30 mm circle, the circumference can be calculated using the formula C = 2πr, where r is the radius (half the diameter). With a radius of 15 mm, the circumference would be C = 2 x π x 15 mm ≈ 94.25 mm. This measurement demonstrates the roundness of the circle based on its size and shape.
Well, honey, the radius of a circle is always half of the diameter. So if the diameter is 30 mm, the radius would be 15 mm. It's basic math, darling. Hope that clears things up for you!
If the radius of a circle is twice the diameter. The outer diameter of a circle the size of a circle. 32.25 mm = 1.27 inches
A 4 mm circle would have a diameter of 4 millimeters, meaning the distance across the circle passing through its center would be 4 mm. This circle would be relatively small, about the size of a standard pencil eraser. In terms of area, the circle would cover approximately 12.57 square millimeters.
There are 10 mm in a cm, so .85 cm is 8.5 mm.
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
The diameter of a circle that has a circumference of 113 mm is about 35.97 mm
The circumference of a circle with a diameter of 110 mm is 345.58 mm
The circumference of a circle that is 16 mm in diameter is 50.27 mm
A circle with a radius of 6 mm has a circumference of 37.7 mm
If the circle's circumference is 58 mm then its diameter is 58/pi which is about 18.462 mm
A circle with a radius of 50 mm has an area of 7853.98 square mm
Circumference of a circle = π × diameter = π × 80 mm = 80π mm ≈ 251 mm
An average thumb is about 40 to 60 mm long. A business card is 50 mm by 85 mm. If you make an "OK" sign by touching the tip of your index finger to the tip of your thumb that will make a circle about 40 mm in diameter.
