Answer:
A. 804 cm²
Step-by-step explanation:
Formula :

A = 3.14 × 16²
A = 3.14 × (16 × 16)
A = 3.14 × 256
A = 803.84 cm²
A = <u>8</u><u>0</u><u>4</u><u> </u><u>cm²</u> (rounded)
So, the approximate area of the shown below is 804 cm² (A)

Differentiating w.r.t y,
We get,
<span>2 x (d x/d y) + y (d x/d y) + x + 2 y = 0 </span>
<span>Put
d x/d y = 0 </span>
The equation becomes:
<span>x=2 y </span>
<span>substituting into main equation
We, get
3 y^2 =9 </span>
y= √3
x = <span>± 2√3</span>
Answer:
208.6 gal/min
Step-by-step explanation:
For 2" pipe,
Given Volume = 463.2 gal, time = 12 min
flow rate for 2" pipe
= Volume ÷ time
= 463.2÷12
= 38.6 gal/min
For 4" pipe,
Given Volume = 1730.4 gal, time = 7 min
flow rate for 4" pipe
= Volume ÷ time
= 1730.4÷7
= 247.2 gal/min
Difference in flow rate = 247.2 - 38.6 = 208.6 gal/min
Answer:
G
