Find the zeros of the function, then round to the nearest hundredth

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
