The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
No. Diameter is the distance across. Circumference is the distance around.
Yes.
Yes.
Yes
yes' if they contain the same circumference and diameter then they are congruent(:
Yes
When a circle's diameter is dilated by a scale factor of 0.6, the new diameter will be 0.6 times the original diameter. Since the circumference of a circle is directly proportional to its diameter by the formula C = πd, where C is the circumference and d is the diameter, the new circumference will also be 0.6 times the original circumference. Therefore, the effect of dilating the diameter by a scale factor of 0.6 will be a decrease in the circle's circumference by 40%.
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
No. Diameter is the distance across. Circumference is the distance around.
Then they are similar.
The formula for the circumference of a circle is: C=2r(pi) Since diameter is the same as 2r, the circumference is 3476(pi).
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.
YES!!! THey would be congruent circles; tjhat is appear to be the same size.
