Step-by-step explanation:
Answer:
<u>The cover has diameter of:</u>
- 20 feet + 2*12 inches = 20 feet + 2 feet = 22 feet
a.
<u>Area of the pool cover:</u>
- A = πd²/4 = 3.14*22²/4 = 379.94 ft²
b.
<u>The length of the rope:</u>
- C = πd = 3.14*22 = 69.08 ft
Fourths, (1/4), (.25), (25%)
V = (4/3)π*r^3
V' = 4π*r^2*r'
600 cm^3/min = 4π(30 cm)^2*r'
r' = (600 cm^3/min)/(4π(30 cm)^2) = 1/(6π) cm/min
The rate of change of radius is about 0.05305 cm/min.
