Measure the angle between the lights and use trigonometry to calculate the base of the skinny triangle.

    can you do it?

  • Vernon Taylor Dec 29, 2018

    It has been many years since I last tackled such a problem and would have to resort to the textbooks for formulae and tables but the big problem would be accurately measuring the angle between the lights.
    The best way to obtain an accurate angle would probably be more calculations from the triangle formed between 2 equally long straight poles or rods aimed at the lights from a common point and then measuring the distance between them to obtain a known base length.

    A rough calculation could be made by dividing the length of the rod into the 30 mile distance and then multiplying the result by the base length to discover approximately how far apart the lights are.

SOURCE: distance

You say it is 30 miles away because you know the route to the specified location. 16 miles means that the distance directly from your location to the specified location.

SOURCE: What is the distance represented by 3.2 inches if the scale 1 inch = 30 miles is used

This would come out to 90.6 miles, so 90 and a little over 1/2 mile. Good Luck Friend.

How can I change from meters to Yards?

Meters. 1 m is equivalent to 1.0936 yards, or 39.370 inches. Since 1983, the metre has been officially defined as the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458 of a second.

What is the radius of a 3/4 acre circle (in feet)

Oh wow, lots of math going on here...

There are 4840 square yards in an acre and 9 square feet in a square yard (4840 x 9 = 43,560).

An acre is an old timers measurement used in agriculture...
it was 4 poles wide and 40 poles long. A pole is equivalent to sixteen and a half feet. So back then, an acre was a piece of farming land 660 feet long (220 yards or one eighth of a mile) and 66 feet wide (22 yards or one eightieth of a mile).

Acre is a measure of area, which would be square feet.

Feet are a measure of distance.

The best you could do is something like this:
An acre is 43, 560 square feet.
Draw/imagine a square or a rectangle that would cover that much area.

If it is a square, it would be (approximately) 208.7 feet on each side.

Its perimeter (the distance around it if you walk an imaginary fence around you acre-sized plot) would be 834.8 feet.

Trying to to figure out an acre of 'Circle' - hmmmmm???

Radius = 1/2 of Diameter

sorry, just can't wrap my head around this to come up with the correct equation.
maybe we can get lucky with some other brainiac taking what I did provide and come up with a solution for you?

Square - It would be 208.7 feet across if you walk across it, and the same if you walk the other way across it.
