Between 20 and 28 students signed up for the chess club. the students could not be divided exactly into groups of 2,3,4 or 5. how many students signed up for the chess club? show your work.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
