Step-by-step explanation:

Your multiplying by 5

1 x 5 = 5

2 x 5 = 10

3 x 5 = 15

4 x 5 = 20

B = 5 x A

Step-by-step explanation:

1 x 5 = 5

2 x 5 = 10

3 x 5 = 15

4 x 5 = 20

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
