It is: circumference/radius = 2*pi

A wheel is in the shape of a circle. The formula for the circumference of a circle is 2πr where r is the radius. But, the diameter of a circle is twice the radius so this equation can be written, Circumference = πd where d is the diameter. The Circumference is therefore π times as big as the diameter, π = 3.142 or 22/7 approx.
Given a diameter d, the circumference of a circle is Pi*d. Thus the circumference is Pi times larger than the diameter.
Circumference = 2*pi*radius or pi*diameter Circumference = 36pi inches

The Earth is 3.64 times larger than Moon's Circumference. (Earth's Circumference) 39,843 divide by (Moon's Circumference) 10,921=3.64
100,000 times
2 pi times greater-- roughly 6.28 times greater.
The Earth's radius is6 378.1kmSo that means that the earth is 1.88 (almost 2) times larger.

Two times larger.
The sun will be ten times larger in diameter (and radius) than the star in question. this does not mean it will be 10 times the volume or ten times the mass though.
Between 10 to 100 times the radius
