Ah, what a delightful question! The radius of a circle fits into the circumference of the circle exactly 2 times. Just imagine the radius wrapping around the circle, giving it a warm hug, and then doing it one more time for good measure. It's a beautiful relationship between the radius and the circumference, creating harmony and balance in the circle's lovely shape.

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
8 times
The Earth's circumference is about 10 times larger than the Moon's circumference.
100,000 times
Earth's radius is about 6,371 km, so Earth's radius is approximately 1.88 times larger than Mars.
2 pi times greater-- roughly 6.28 times greater.
The sun has a radius of approximately 696,340 kilometers, while a star with 0.1 solar radius would have a radius of 69,634 kilometers. To calculate how many times larger the sun is, we divide the sun's radius by the smaller star's radius: 696,340 km / 69,634 km = 10. Therefore, the sun is 10 times larger than a star with 0.1 solar radius.

The radius of the Sun is about 109 times larger than the radius of the Earth.
Given a diameter d, the circumference of a circle is Pi*d. Thus the circumference is Pi times larger than the diameter.
Two times larger.
