What would you do to find the arc length around 5/8 of a circle?

5/8 * 2 * pi *r

Step-by-step explanation:

First find the circumference of the circle

C = 2 * pi *r

Then multiply it by the fraction  of the circle  ( arc length) you wish to find

5/8 * 2 * pi *r

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
