Determine whether the two expressions are equivalent. If so, tell what property is applied. If not, explain why. 1. 8 x (4 x 3) and (8 x 4) x 3
2. 17 + 12 and 12 + 17

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

$649.60
