step-by-step explanation:

a. is correct

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

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
