The diameter of the star would be 197.07 times the suns diameter, 1.83 astronomical units, about 170 million miles or 270 million kilometres.

What is the distance of an object that has an angular diameter of 100 seconds of arc and a linear diameter of 30 meters?
30 meters subtends 100 seconds of arc.I get a distance of 61,879 meters.
A dime is 1.8 cm in diameter At what distance from your eye would you have to hold a dime so that it has the same angular dia as a full moon?
2.3 inches
Use the small-angle formula to find the angular diameter of mars when it is closest to Earth how does that compare with the maximum diameter of Jupiter?

What is the angular diameter of the moon just above the horizon?
163.36
Do the sun and moon have the same angular diameter?
It is true that as seen fro the earth the sun and the moon have roughly the same angular diameter. It is for that reason that total solar eclipses are so spectacular.
What is distance of the begin of the Orion's belt and the end of it?
The stars at the two ends, Alnitak and Mintaka are at a distance of 387 and 380 parces (1262 and 1239 lightyears) respectively. Due to the relatively small angular separation, the distance between the stars is approx 7 parsecs = 23 lightyears.
A marble has a diameter of 2 cm At what distance would the marble have an angular diameter of 1 arc second?
6.5cm
What is the angular diameter of Earth as seen from the moon?
Since Earth has about 4 times the diameter of the Moon, the angular diameter of Earth, as seen from the Moon, is about 4 times larger than the angular diameter of the Moon, as seen from Earth. Since the Moon's angular diameter as seen from here is about half a degree, that would make Earth's angular diameter about 2 degrees.If you wish, you can look up more exact figures and do more precise calculations, but it is hardly worth the trouble, since there is some variation in the distance from Earth to Moon anyway.

What is the angular size of circular object with a 2 inch diameter viewed from a distance of 4 yards?
It is 0.8 degrees.
What is the angular size of a circular object with a 2 inch diameter viewed from a distance of 4 yards.?
It is 0.8 degrees.
What is the angular size of a circular object with a inch diameter viewed from a distance of 2 yards?
It is approx 0.8 degrees.
What is the angular size of a circular object with 1 inch diameter viewed from 4 yards?
To find the angular size, we need to convert the distance to the object into radians. 4 yards is approximately 12 feet or 144 inches. The angular size can be calculated as the diameter of the object (1 inch) divided by the distance to the object (144 inches), which equals approximately 0.0069 radians.
What causes the angular diameter of the moon to increase and decrease over time?
The change in its distance from the earth. The distance changes by about 43,000 km which equates to about 4.8 minutes of arc.
What is the diameter of Mars if it's angular size is 008276?
You would also have to know its distance. This varies a lot, depending on where in their orbits Earth and Mars are.
Which is bigger full moon or crescent moon?
The diameter of the Moon doesn't change. The apparent (or angular) diameter changes a little, depending on the distance of the Moon from Earth, but this is not directly related to the phases of the Moon.
What is the Angular size of a circular object with a 1 inch diameter viewed from a distance of 2 yards?
Since it is a small angle, just divide the diameter by the distance. Be sure to convert everything into the same units first. The answer will be in radians.
