What is a star that has a low surface and large diameter relaed to the sun?

Question not worded well. Sounds like right out of homework.
Do I read "low surface" temperature? -- Large diameter relative to the Sun?
By the HR classification, we might be talking about a giant star or a supergiant, or even a hypergiant -- certainly not a main sequence star.
A lower surface temperature, say a K class, or M, or even L, indicates that the star would appear orange to red in color, if it is capable of visible emission.

What is the giant star?
The largest stars - that is, largest in diameter - are usually red. This is related to the fact that their surface temperature is relatively low. They still radiate huge amounts of energy though, due to their large surface.

What is the difference between a giant star and a supergiants?
A supergiant simply is a large giant - so, it is larger (in diameter) than a "regular" giant star.
What star takes one thousand of our years to rotate once on its axis?
I don't know whether such a star exists, but that might be the case for a star with an extremely large diameter.
How can a small star could look brighter from earth than a bigger star?
It would look brighter if it is closer to Earth. It is also possible for a small star (small in diameter) to have a higher surface temperature, i.e., to emit more light per square meter of its surface.
How does a star's temperature affect its absolute magnitude?
The absolute magnitude of a start will increase both:* If its surface temperature increases, and * If its diameter increases.
What stars are cool and bright stars?
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
What are super giants?
it is a very large star of high luminosity and low surface temperature.....=)))))
Is the size of a star the only factor that setermines its absolute magnitude?
No. I assume you mean the star's diameter. The area is proportional to the square of the area - so the bigger the star, the brighter it will be - other things being equal. However, the star's surface temperature also affects its brightness.
Is the sun a large star or a very large star?
It is a large star
What is the diameter of the Texas Star ferris wheel?
the diameter is 87 meters
What precipitation is 6 millimeters in diameter?
A diameter is the distance from one side of a spherical or circular object, through the centre, to the other. It can be as small as an atomic sub-particle or as large as a red super-giant star. There is absolutely no way that 6 millimetres can be "converted" to diameter.
