You are about to begin work on a swimming pool in your yard. The first step is to have a hole dug that is 30 feet long, 18 feet wide, and 6 feet deep. You will use a truck that can carry 20 cubic yards of dirt and charges
$30 per load. How much will it cost you to have all the dirt hauled away?
The cost is $

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

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
