Circumference of an arc formula
WebThe formula sheet has formulas for area and circumference, plus the statement: The number of degrees of arc in a circle is 360. If you don't remember how to do these, it would be great to practice them, plus the … WebBecause the formula 2 π r is the formula for the circumference of the WHOLE circle. But they only want the arc length of 3/4 of the circle. So the answer of 8π was the answer for the whole circle so you have to multiply it by 3/4 which gives you 6π, The answer to the arc length that they asked for.
