If the radius of a star increases by a factor of 6 the surface area of the star increases how many times?

When radius of star increase by 6 factor then area of star will increase by a factor of 36.

Explanation:

As we know that

Area of star A given as

Where R is the radius of star.

Area of star when radius become 6 times

So

We can say that when radius of star increase by 6 factor then area of star will increase by a factor of 36.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
