Answer: 125 ft cubed
Step-by-step explanation:
Answer:
1.92cm
Step-by-step explanation:
Circumference of a circle is computed using the formula:

Where:
r = radius
π = 3.14
Since the radius is the distance of the center of the circle from any point of the circle and the diameter is the measure of a straight line that goes across the center of the circle from one side to the other, radius is half of a diameter. So the diameter = 2r.
We can then use the diameter to solve for the circumference by using the formula"

So we just plug in what we know in the formula:


where

is the angle between the vectors. You have

The vectors would be orthogonal if the dot product had been zero, but that's clearly not the case.
They would be parallel if the angle turned out to be

or

, but that's also not the case.
So the answer is neither.
2 ( which came from 2y ) divided by 6 is 3.
