Answer:
5.625 inches
Step-by-step explanation:
Given that:
Total Rainfall in inches (P) = 8 inches
The runoff volume (in inches) Q = ???
The curve number CN = 80
Recall that: The runoff volume can be calculated by using the formula:
for P > 0.2S
Q = 0 for P < 0.2S

where:
curve number CN = 80

S = 2.5 inches
Since the rainfall (P) is greater than 0.25
Then:




Q = 5.625 inches
Thus, the runoff volume = 5.625 inches
Answer:
B) 3√2
Step-by-step explanation:
FH = √GH²+FG² = √18 = 3√2

Volume (V) of a cylinder is the area of circular base (pi×r^2) times it's length/height (h):

h = 20.5 ft
diameter (d) = 1 1/5 × h, 1 1/5 = 6/5 = 1.20
d = 1.20 × 20.5 = 24.6 ft
radius (r) = 1/2 d = 24.6/2 = 12.3 ft
