A climber starts descending from 574 feet above sea level and keeps going until she reaches 80 feet below sea level. How many feet did she descend?

654 feet

Step-by-step explanation:

a climber starts from 574 ft above sea level till reaches 80 below sea level.

how many feet did the climber descend?

= 574 to 0, then 0 to 80

= 574 + 80

= 654 feet

22

step-by-step explanation:

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
