The circumference of a circle can be found using the formula C = 2r. Which is an equivalent equation solved for r? r = C r = C2 r = r equals StartFraction C Over 2 pi EndFraction. r = r equals StartFraction 2 pi Over C EndFraction. HURRY IM BEING TIMED

Answer:r equals StartFraction C Over 2 pi EndFractionwe know thatThe circumference of a circle is equal to\(C=2\pi r\)wherer is the radius of the circleSolve for rThat means -----> isolate the variable rDivide by 2π both sides\(\frac{}C{}{}2\pi{}=\frac{}2\pi r{}{}2\pi{}\)Simplify right side\(\frac{}C{}{}2\pi{}=r\)Rewrite\(r=\frac{}C{}{}2\pi{}\)sor equals StartFraction C Over 2 pi EndFraction
