What is the circumference of a 20 foot diameter circle?
The circumference of a circle is 20 feet. What is the diameter? c≈15.708 ft. c≈15.708 ft.
How do I figure out diameter?
The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.
What is the circumference of 10cm?
Answer. We know that C = πd. Since the diameter is 10cm, we know that C = π x 10cm = 31.42cm (to 2 decimal places).
