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%
