The Morgan family and the Kim family each used their sprinklers last summer. The water output rate for the Morgan family’s sprinkler was 15 L per hour. The water output rate for the Kim family’s sprinkler was 25 L per hour. The families used their sprinklers for a combined total of 70 hours, resulting in a total water output of 1350 L.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

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
