Answer:
$21
Procedure:
(6) (2) = 12 (3) (3) = 9
Verification
12 / 2 = 6 9 / 3 = 3
3.36242487588 is the answer
Step-by-step explanation:
We know that
Radius = Diameter/2
=> Radius = 2/2
=> Radius = 1 in
Now,
Volume of cylinder = πr²h
=> π × (1)² × 9
=> 9π in³
Since it is filled ⅔ of the volume
So,
Water to be putted = ⅔ × 9π = 6π in³
