Answer:
8 hours.
Step-by-step explanation:
The initial water level is 24.8 meters, and the rate of water level drop is 2 meters/ hour, that means after
hours the water level
will be

Now we want water level to be 8.8 meters, I.e
, therefore, we have:

we solve the equation for
:

it will take 8 hours for the water level to drop to 8.8 meters.
Rectangle = 18 x 6 = 108
Circle: 3.14 x (3)^2 = 3.14 x 9 = 28.26
<span>semicircle: 28.26 / 2 = 14.13
</span>
108 + 14.13 = 122.13
answer
122.13 cm^2
Answer:
Step-by-step explanation:
Use the Pythagorean Theorem.
base² + height² = hypotenuse²
6² + 8² = hypotenuse²
100 = hypotenuse²
hypotenuse = √100 = 10 meters
Answer:
23 maybe because there is a 90 degree angle
