Yes
Then they are similar.
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
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
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
Yes.
Yes
Then they are similar.
YES!!! THey would be congruent circles; tjhat is appear to be the same size.
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
The circumference of a circle with a diameter of two is about 6.28
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.
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
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.)
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
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
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.
