Best Answer

The circular length of the arc = Pi/180 x angle in degrees x radius

L = Pi/180 x 1/3600 x 40 = 0.000193925 ft. = 0.00233 inches

Just slightly more than two-thousands of an inch.

A second of arc.

An arc second is a measure of angular separation, not of distance. It is therefore an inappropriate unit for measuring the distance to a star.

there are 60 seconds in one minute. An arc minute is 1/60 degree and an arc second is 1/3600 degree

A degree of latitude is approximately 69 miles, and a minute of latitude ... At a latitude of 45 degrees, a degree of longitude is approximately 49 miles.

One arc second is one 3600th of a degree.

An arc second is 1/60th of an arc minute and 1/3600th of a degree. This means there are 60 arc seconds in an arc minute, and 3600 arc seconds in a degree.

Arc radius 23 feet 9 inches (7.24 m), no less than 3 feet (0.91 m) from each sideline

The measure of the central angle divided by 360 degrees equals the arc length divided by the circumference. So 18 degrees/360 degrees=arc length/(9 feet*2pi). 1/20=arc length/18pi feet; arc length=9pi/10 feet. It's refreshing to answer a question that is written with grammatical accuracy!

0.01 arc second is one hundredth of an arc-second.An arc-second is one sixtieth of an arc-minute. (There are about 30 arc-seconds across the visible diameter of the Sun or Moon).An arc-minute is one sixtieth of a degree.A degree is one three hundred and sixtieth of a circle.So a hundredth of an arc-second is a good resolution for a fine telescope.If you have an image of the Moon where the moon is 3000 pixels wide (probably twice the width of your computer screen) then 0.01 arc-second is one pixel.
