How long is a circle if the radius is 36?
72
If a circle needs 8 360 degree rotations to roll 8 meters it's radius is how many meters long?
Circumference is 1 meter so radius = 0.5/pi meters = 0.160 meters/160 millimeters to the nearest thousandth
Why is the circumference alsways 3.14?
The circumference is not always 3.14 , The circumference of a circle is always (pi) times as long as the circle's diameter. (Pi) is a number that can't be exactly written down with digits, that begins with 3.14 . It's defined as the ratio of any circle's circumference to the same circle's diameter. The reason is because that's one of the properties of the thing that we call a "circle".
How do you find the radius given the chord length?
If you are given a chord length of a circle, unless you are given more information about the chord, you can not determine what the radius of the circle will be. This is because the chord length in a circle can vary from a length of (essentially) 0, up to a length of double the radius (the diameter). The best you can say about the radius if given the chord length, is that the length of the radius is at least as long has half half the chord length.
How far does the tip of the minute hand travel in 2 minutes if it is 5 cm long?
The circumference of any given circle can be calculated if you know the radius, in this case a 5cm radius, so (pi*5cm)=15.71cm of circunference and if you add another full turn the next minute then 15.71cm more....so 31.4cms traveled. But, If you are in the highway counting this, traveling at 75mph then you and the watch and its minute hand traveled 1 1/4miles.
How many centimeters are in a radius?
A radius is not a specific unit of measurement - the radius of a circle is the measurement from the centre of the circle to any line on the circle's circumference. The word "radius" is derived from the Latin word for "ray" but was also used to refer to the spoke of a chariot wheel.
What is the circumference of a circle if it is 13 cenatmeters long?
Circumference of a circle = 2*pi*radius or pi*diameter
An arc 14cm long on the circumference of a circle subtends an angle of 128degrees.What is the radius of the circle?
The radius is: 6.267 cm
What is the circumference is circle that is 24 meters about how long is the diameter if pie is 3?
Circumference of a circle = 2*pi*radius or diameter*pi Its diameter = circumference/pi
If the circumference of a circle is 94.2ydhow long is the radius?
radius = 94.2/(2*pi) = 14.99239564 or about 15 yards
If the circumference of a circle is approximately 113 yards about how long is the radius?

40.8cm
Is the diameter of a circle bigger or smaller then the radius?
The diameter is twice as long as the radius. d = 2r The diameter is basically a line through the center of a circle while a radius is from the center to the circumference of a circle.
How long is the radius of the circle 28yds?
It depends on what is meant by 28 yards: diameter? circumference?

Circumference of circle: 31.4 inchesArea of circle: 78.5 square inches
What is the radius of a circle in which a 30 degrees arc is 2 inches long?
360/30*2 = 24 = circumference of the circle 24/2*pi = 3.819718634 inches = radius of the circle
What is the diameter of a circle that is 72 long?
What aspect of the circle is 72? You will get a different answer depending on whether 72 refers to the radius or circumference.
