Circle with an r
WebJul 3, 2024 · You can calculate the circumference of any circle if you know either the radius or diameter. The formulas are: C = πd C = 2πr where d is the diameter of the circle, r is its radius, and π is pi. So if you measure the diameter of a circle to be 8.5 cm, you would have: C = πd C = 3.14 * (8.5 cm) C = 26.69 cm, which you should round up to 26.7 cm WebThe circle R symbol (®) means that a mark is federally registered with the US Patent and Trademark Office, either on the Principal Register or Supplemental Register.
