As a block of ice melts, its weight changes from lb to 2 1/2 lb to 1/2/b. This change takes 1/2
hr.
The ice melts at a constant rate. At what rate
does the weight of the ice change?​

answer: 40.95

step-by-step explanation:

the correct answer is d

hope this

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
