What expression can be used to find the radious of a circumference of 29?

Since the formula for circumference is Pi (3.14) times the diameter, you can work it backwards to find the radius. You first divide the circumference, 29, by Pi (3.14), then divide it by 2 since the diameter, which you just found, is twice the radius. (In case you don't know, the diameter is the distance across the circle, and the diameter line passes through the center point. The radius is the distance from the center of the circle to the outside. Therefore, the radius is half of the diameter.) So, in this case, the radius of a circle with a circumference of 29 units would be approximately 4.6178 (rounded).
Hope I made sense.

Which equation can be used to find circumstance C of a circle with radius that measures 16 ft?
I don't know if this is what you are after, butthe circumference (not circumstance) C is 2*pi*r where r is the radius (not radious, as you spell it).
What formula is used to find the diameter when you know the circumference?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
How do you find the radius with the circumference and area having the same value?
Please note that a circumference is a linear measurement (for example, meters), while area is an area measurement (for example, square meters), so the "equality" depends on the units used. Anyway, all you need to do is write the expression for the circumference, and the expression for the area, then put an equal sign in between - since the problem states that the two are equal. Then solve this equation.
What formula is used to find the circumference when you know the radius?
Circumference=2*pi*radius
How is pi used to find circumference of circles?
Pi times the diameter of a circle gives its circumference.
How can you use radious in a sentence?
The word radious should never be used in a sentence since its spelling is incorrect and it is not possible to determine whether the intention was to write radius or radios.
