What is the distance between the pivot point and the marking point of a compass when drawing a circle?

I'm sure you have seen or used a compass already. The pivot point is the needle part. It is called as such because it is the point where the compass turns so that the movie end of the other leg of the compass can make arcs.

As you create a circle using a compass, that same distance between the two legs of the compass is the radius of the circle. By definition, a circle is a round two-dimensional figure that is composed of a series of points that is equidistant to a fixed point inside the circle. That point is called the center of the circle represented by the pivot or needle part. The equal distance of all the points along the circumference is the radius.

The water pressure for a standard fire hydrant is 20 pounds per square inch. Convert this to

<h3>Answer: 2880 pounds per square foot</h3>

==========================================================

Explanation:

psi = pounds per square inch

1 foot = 12 inches

1 square foot = 144 square inches

I squared both sides to get the second equation. Think of a 12 by 12 square representing 12 inches along each side, so that leads to 12*12 = 144 square inches being the same as 1 square foot.

That last equation helps us convert from square inches to square feet like so:

$20 \text{ psi} = \frac{20 \text{ pounds}}{1 \text{ square inch}}\\\\20 \text{ psi} = \frac{20 \text{ pounds}}{1 \text{ square inch}}*\frac{144 \text{ square inches}}{1 \text{ square foot}}\\\\20 \text{ psi} = \frac{20*144}{1*1}*\frac{\text{ pounds}}{\text{ square foot}}\\\\20 \text{ psi} = \frac{2880 \text{ pounds}}{1 \text{ square foot}}\\\\20 \text{ psi} = 2880 \frac{\text{ pounds}}{\text{ square foot}}\\\\20 \text{ psi} = 2880 \text{ pounds per square foot}\\\\$

Notice in the jump from the second step to the third step, we have the "square inches" unit cancel out when dividing. All that's left is "pounds" up top and "square foot" down below.

In short, we simply multiply by 144 to go from 20 to 2880.
