How do you find the diameter when you only have the arc measure and length?

Suppose the angle of the arc is x radians and the length of the arc is a units.
Then, if the radius of the circle is r units, a = rx or r = a/x
So d = 2a/x units of length.

How do you find the diameter of a circle if you only now the arc length and measure?
measure/360=arc length/circumference. C=pi*diameter, so you now have (known value)/360=(known value)/(pi*diameter). With only one unknown value, you can now find the diameter.
How do I find the diameter of a circle only having an arc length?
If you have only the arc length then you cannot find the diameter.
How do you find the diameter of a cylinder when you only know the length?
If you only know the length, and nothing else, you can't. If you know the length and the volume, you can calculate the diameter.
Where do you measure the curve of a cylinder to find its volume?
A good place to measure is the diameter of the circular end. That gives you the area of the circular end, and the only other number you need in order to calculate the cylinder's volume is its straight length.
How do you find the length of the sides of a triangle when you only know one side and no angles?
Measure them

Do you have to find the radius for diameter?
Not necessarily. The diameter is only twice the radius, so that's an easy way to find the diameter. However, if you have the circumference, you can divide by pi to get the diameter, or just measure across the circle.

Measure them
Where do you find the radius?
A radius is the distance from the center point of a circle to the outside. To find the radius, you'd draw a line from the center of a circle straight out until it hits the circle itself, then measure the length of the line you just drew. If you are given a diagram where only the diameter is shown (the distance from one side of the circle to the other), just take half the diameter.
How do you find the cirumfrence with only the diameter?
circumference = pi*diameter
How do you find the diameter of water?
Only circles (or spheres) have a diameter
How do you find the diameter if you only have the radius?
Multipy by 2 for the diameter
How do you find the square footage of a window?
Length x width. If you are figuring egress, you can only measure the actual opening size.
How do you find the length of a rectangle knowing ONLY the diagonal and the length?
If by that you mean knowing only the diagonal and the width, then by the formula a2+b2=c2, where a is the length, b the width and c the diagonal. To find the width b, you need to calculate sqrt(c2-a2). For example, the width of a rectangle with length 3 and diameter 5 is sqrt(52-32)=4
