Are circles congruent?
Two figures are congruent if you can "pick one up" and then place it down on top of the other one in such a way that the two exactly overlay each other... in other words, if they are the exact same shape and size. So, any two circles will always have the same shape, but not necessarily the same size. Only circles that have the exact same size (as measured by matching radius, diameter, circumference, or surface area) are congruent.
What is the circumference of a 12 foot diameter circle?
Circumference= 37.68 feet. All you have to do is multiply the diameter by pi. Same with radius. Multiply the radius by two to get the diameter then do diameter times pi.(pi= 3.14 or 22 over 7.)
Pi is the ratio of a circles circumfrance to its what?
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
How do you find the radius of a circle if you have the circumference?
Easy to do. First, divide the circumference by Pi (about 3.1416). The result is the diameter. Now, divide the diameter by two to get the radius.
If there are two circles and the small one has diameter of 20 what is the radius of the big circle?
You need some more information about any of the circles, or about the relationship between the two circles, to answer this question.
Do two circles have the same diameter if they have the same circumference?
Yes.
Do two circles with same diameter have same area or circumference?
Yes
If Two different circles have same circumference?
Then they are similar.
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.
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
What is the circumference of a circle with the diameter of two?
The circumference of a circle with a diameter of two is about 6.28

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 circumference of a 12 foot diameter circle?
Circumference= 37.68 feet. All you have to do is multiply the diameter by pi. Same with radius. Multiply the radius by two to get the diameter then do diameter times pi.(pi= 3.14 or 22 over 7.)
What formula do you use to find the radius diameter and circumference of a circle?
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
How do you get a circles diameter?
3 ways 1) measure it 2) if knowm, multiply the radius by two 3) if known, divide the circumference by pie-3.4 hope this helps
What is the formula for the radius of a circle when you have the circumference?
well the circumference is equal to pi times the diameter, so all that you have to do is divide the circumference by pi to get the diameter. Then you divide the diameter by two to get the radius.
