21. Calculate the mean, median, mode, variance and standard deviation for the following set of data. Show all calculations, (10.1, 20.2, 16.7, 9.9, 10.1, 244, 19.9, 20.0)

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

hm let me think hm think think hm think yes

what is the problem ?
