May 6, 2024 · The circumference of a circle with a diameter of 20 mm is 62.8 mm. This is calculated using the formula C = π × d, where π is approximated as 3.14. By substituting the diameter into the formula, we find the result.

Dec 25, 2024 · The area of a 20mm circle is approximately 314 square millimeters (πr², where r is the radius, which is half the diameter). This is significantly different from the linear measurement of the diameter alone.

Apr 28, 2022 · For a circle with a diameter of 20 mm, it's radius, which is half that, will be 10 mm. The area (A) of a circle is pi (about 3.1416) times the radius (r) squared (r2). Here's how we work...

How to find the area of any a circle given its diameter. The area of a circle with diameter of 20 is equal to 314.2. See the solution steps here.
