What is the outside of a circle known as?
Oh, dude, the outside of a circle is called the circumference. It's like the circle's boundary or edge, you know? So, if you're ever lost in a circle, just look for the circumference to find your way out.
How do you find the diameter of a circle if it has a circumference of 500 ft?
Easy. Just divide the circumference by Pi (3.1416) to calculate the diameter.In your example, it would look like this: 500 / Pi (3.1416) = 159.15 foot diameter (rounded).
If the circumference of a circle is doubled what happens to the diameter?
If you double the circumference. the diameter like wise would double.
Is the area of a circle called circumference?
No. The circumference of a circle is the length around the circle, much like the perimeter of a square.
If the radius of a circle is tripled what happens to the circumference?
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
