Circumference of a circle if diameter is 6cm?
Circumference of a circle is 2πr (two x Pi x the radius of the circle)Pi is usually taken as 3.14 for simple calculations - see here http://en.wikipedia.org/wiki/Pi for a longer determination of Pi.The radius is half the diameter.Thus, a circle with a diameter of 6cm has a circumference of 18.84cm
Is the circumference always longer than the diameter?
Yes. Always exactly (pi) times as long. "Pi" is slightly more than 3.14 .
How much longer is the perimeter of a square than the circumference of a circle if the circumference of the circle is approximately 11 centimeters and the diameter is 3.5 centimeters?
O = pi*D cm = 3,14 * 3,5 cm = 11 cm The circumference from the inside square is Li = 4*(Root from (2*(D/2)square))= 4*Root 2,47 =9,89 cm. The circumference from the outside square is Lo = 4* D = 14 cm.
What is the difference of oval and circle?
A circle has the same diameter around its border, while an oval is longer than its width.
Which is longer radius or diameter?
Diametre is, since diametre = 2*radius
Is circumference shorter or longer then radius or diameter?
It's longer than both. The circumference - is the distance around the circle... The diameter - is the distance across the circle, passing through the centre... The radius - is the distance from the centre of the circle to the edge.
How many times longer is the circumference of a circle than its diameter?
It is larger than the diameter by a factor of Pi (about 3.1416).

Which is longer the circumference of a circle with a five inch diameter or the perimeter of a square that measures 4 inches on a side?
The square because its perimeter is 16 inches while the circumference of the circle is 15.708 inches.
Is the circumference always longer than the diameter?
Yes. Always exactly (pi) times as long. "Pi" is slightly more than 3.14 .
If a circle has a diameter of 15 inches can it also have a chord of 20 inches and how?
No. A chord is a straight line drawn between any two points on the circumference of a circle. The longest chord is when the points are on opposite sides of the centre of the circle (and passes through the centre of the circle). The straight line which joins the points on opposite sides of the centre (through the centre) is called the diameter of the circle. Therefore the longest chord possible is the diameter of the circle. A circle with a diameter of 15 in can have a chord with a maximum length of 15 in.
What is the chord of a circle that is always smaller?
There is no chord that is always smaller since, in the limit, the chord reaches a single point on the circumference - when it it is no longer a chord!
Can a chord of a circle ever be longer than the diameter?
The longest chord in a circle is the diameter. So, no.
Is a chord or a diamater longer?
In a circle, there are 1 or more chords, and only always 1 diameter. The diameter goes through the middle point in a circle and connects 2 points on a circle. A chord does not have to go through the middle, but can. The diameter always counts as a chord. So, either, both the chord and diameter are the same length, or the chord is shorter. I hope this answers your question! (:
What is the effect of the length of the radius to the movement of objects around the circle?
Well, the longer the length of the radius is, the more the circumference is (because you multiply the radius by pi (approximately 3.1415) to get the circumference, so the circumference is longer, making the journey of objects around the circle farther.
How much longer is the circumference of a 12 inches diameter pizza have than an 8 inches diameter pizza?
Circumference of a circle = pi DCircumference of the big one = 12 piCircumference of the small one = 8 piDifference = (12 pi - 8 pi) = (12 - 8) pi = 4 pi = 12.5664 inches (rounded)
What is the formula for circumference and area?
of what? Does it really take that much longer to type in "of a circle".
