Is radius half radius?
No. Radius is half of the diameter.
How do you get from the radius to the circumference?
(radius+radius) times pi
How do you find a circumference of a circle if the radius is a fraction?

Who was radius named after?
I am sorry radius was named after george radius who was a scientisit
How do you find the radius of a circle if you know the radius?
You already know the radius.
What is size of polaris star?
Polaris is a yellow super-giant with two smaller companions, Polaris Aa has a radius which is 46 +/- 3 times the Sun's radius.
How much larger is polaris than your sun?
Polaris has a radius around 30 times that of our own sun.
What is larger in size Pollux or Polaris?
Pollux is larger than Polaris. Pollux, a binary star in the constellation Gemini, has a radius about 8.5 times that of the Sun, while Polaris, the North Star in the constellation Ursa Minor, has a radius approximately 2.5 times that of the Sun. Thus, Pollux is significantly larger in size compared to Polaris.
What is the size of the star name polaris?
The main star in the Polaris system has a mass of 4.5 Suns and a radius which is 46 +/- 3 times as big as the Sun's.
How big is earth compared with polaris?
Polaris has a radius which is around 5000 as big and so it occupies a volume which is approximately 125 billion times as large.
How many inches long is the north star?
The radius of Polaris in inches is: 27,400,032,000 inches.
What is the color size and apparent brightness of polaris?
The main star in the Polaris system, Polaris Aa, is a yellow super-giant, with a radius which is 46 +/- 3 times that of the sun. Its apparent magnitude is 1.98 but it is a Cepheid variable.
What is the largest circle that you can draw around Polaris without running into the horizon?
It's the circle whose radius is the same as your north latitude. (That means it depends on where you are, and if you're south of the equator, Polaris is below your horizon anyway and there is no such circle.)
Which star is larger in size Polaris or Centauri b?
Polaris, also known as the North Star, is significantly larger than Proxima Centauri b, which is an exoplanet orbiting the red dwarf star Proxima Centauri. Polaris is a supergiant star with a radius about 30 times that of the Sun, while Proxima Centauri is a small, low-mass star, about 14% the mass of the Sun. In terms of size, Polaris is vastly larger than Proxima Centauri b's host star.
What is the altitude of Polaris as seen from New York City if the terrestrial coordinates are 41 degrees north 74 degrees west?
Polaris makes a little circle of about 1/3° radius around the celestial north pole every day. But we don't notice that, and it appears to mark the pole itself. So the altitude of Polaris is essentially equal to the observer's north latitude. If he's standing 41° north of the equator, then he'll see Polaris at roughly 41° above his northern horizon.
Is Polaris A a Red Giant?
No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").
Is a red giant a polaris?
No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").
