The formula for the circumference of a circle is c = 2 πr .use this formula for radius of a circle
a) r = 2 πc
b) r = c-2π
c) r= c/ 2π
d) r = 2π/c

Circle d circumscribes abc and abe. which statements about the triangles are true? statement i: the perpendicular bisectors of abc intersect at the same point as those of abe. statement ii: the distance from c to d is the same as the distance from d to e. statement iii: bisects cde. statement iv: the angle bisectors of abc intersect at the same point as those of abe. a. i only b. i and ii c. ii and iv d. i and iii e. iii and iv
