Physics questions and answers. A police officer investigating an accident estimates that a moving car hit a stationary car at 25 km/h. Before the collision, the car left 47-m -long skid marks as it braked. The officer …
Answer:
8.97
Step-by-step explanation:
Statement.
(1). ∠1 is right angle & ∠2 is right angle
(2). ∠1 = ∠2
Reason
(1). Given
(2). Euclid’s Fourth Postulate states that all right angles are equal to one another.
Warning
This is assuming, that we only include Euclidean geometers.
This is because Euclidean geometry only recognise angles between straight lines.
So we have Non-Euclidean geometry for things that are not straight but this raises a question what is a straight line?
A general definition is (A curve is "straight' if tangent vectors stay tangent when parallel-transported along that curve)

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
