A circle with a radius of 100 feet has a circumference of 628.32 feet.
A circle with a radius of 100 units has a circumference of 628.32 units.
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100
100/360 of the circumference of the circle = 10*pi inches
If you double the radius of a circle, you also double its circumference.It's now 200% of what it was originally ... an increase of 100% .See rigorous proof below.===========================================Let radius = rCircumference = 2πrDouble the radius:New radius = 2rNew circumference = 4πrIncrease in circumference = 4πr - 2πr = 2πr = (2πr/2πr) X 100%=100%

The radius of a circle is 1/2 of its diameter
Oh, dude, the diameter of a circle is the distance across it passing through the center, and the circumference is the distance around it. So, if the circumference is 100, we can use the formula C = πd to find the diameter. Dividing 100 by π gives us approximately 31.83, so the diameter would be around 31.83 units. But, like, who really measures circles anyway, right?
If the area is a circle, the circumference is about 7,400 feet.
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 100 feet, so the circumference would be C = π(100) = 314.159 feet.

100 feet.
100. The radius is 1/2 of the diameter.

The formula for finding the area of a circle is pi times the radius squared. Let's find the radius of the circle. 100 pi/ pi= 100. Squarerooted, the radius is 10. The formula for finding the circumference of a circle is 2 times pi times the radius. So, plug in: 2 times pi times 10 equals 20 pi! Your final answer: 20 pi (or, if you use decimals, approximately 62.8)
