Answer:
Assume that the expression is:
r = √(A)/3
Multiply both sides by 3:
3r = √(A)
Finally, square both sides to get:
A = (3r)²
= 9r²
I hope this helps!

Step-by-step explanation:
volume of water flows through the pipe per second= π r² h = 22/7 × ( 3/4)² × 16
= 22/7 × 9/16 × 16
= 22/7 × 9
= 3.14 × 9 = 28.26 cm ³= 28.26/ 1000= 0.02826 litre
0.02826litre = 1 second
1 litre = 1 / 0.02826 = 100000/2826
= 35 .38 seconds
answer = 35.38 seconds

The linear function: y = mx + b.
y(x - 1) = 9 → xy - y = 9 NOT (xy)
y - 5 = x(-x + 2) → y - 5 = -x² + 2x NOT (x²)
y(y - 1) = x + 25 → y² - y = x + 25 NOT (y²)
y - 5 = x - 20 → y = x - 15 YES
Adding in base 3 is very much like adding in base 10, but instead of carrying digits when their sum exceeds 9, we have to watch for when the sum exceeds 2:
