Do two circles have the same diameter if they have the same circumference?
Yes.
Is the ratio of circumference to the diameter of all circles always the same?
Yes
Why are the area and the circumference of a circle the same?
Frankly, I haven't the slightest clue as to what you mean by "the same." The circumference of a circle is defined as pi x 2 x radius, or pi x diameter. The area is pi x radius squared. Therefore, for real circles, these values can only be the same if the diameter measure is the same as the radius squared. This works is the radius is 1 or 2.
What are two ways a circle and a cylinder the same?
The bases of a cylinder are circles and both have circumferences Area of the base of cylinder and a circle is pi*radius2 Circumference of a cylinder and a circle is 2*pi*radius or diameter*pi
What is the formula for the circumference of a circle if the diameter is 8.70 m?
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
Do two circles have the same circumference if they have the same diameter?
Yes.
Do two circles have the same diameter if they have the same circumference?
Yes.
Are circles contrugent?
yes' if they contain the same circumference and diameter then they are congruent(:
Is the ratio of circumference to the diameter of all circles always the same?
Yes
Do two circles with the same area have the same circumference?
YES!!! THey would be congruent circles; tjhat is appear to be the same size.

If the diameter of a circle is dilated by a scale factor of 0.6 what will be the effect on the circles circumference?
All linear dimensions (radius, diameter, circumference, an arc that covers a certain angle, etc.) will scale by the same factor.
What are the charateristics of a circle?
It's a perfectly rounded 2 dimensional shape It can be easily constucted with a compass Its perimeter is better known as its circumference Its diameter spans its circumference cutting through its centre Its radius is half of its diameter It can be concentric with other circles sharing the same centre Its circumference divided by its diameter is the value of pi Its cicumference is 2*pi*radius or diameter*pi Its area is pi*radius squared Its circumference touches a tangent only at a point Its circumference is a full revolution of 360 degrees Its lines of symmetry are infinite
Is the diameter of a circle always the same?
Every diameter of the same circle is the same length, and unless someone comes alongand stretches the circle when you're not looking, the diameter doesn't change.So...YES-----------I disagree...No they are not... all circles would be the same size if that were the case.What remains a constant is that all circles are 360 degrees.==================================The question doesn't ask about " ... the diameter of circles ... ".It asks about " ... the diameter of a circle ... ".The diameter of circles is not always the same, butthe diameter of any one circle is always the same.P.S.: This is not the place to debate the answer.The "discussion area" is.

The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
Do concentric circles have the same circles?
No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.
