Because it is still length. It is measured along a curve (arc), rather than a straight line. It can be found by multiplying the arc angle (in radians) by the radius. So a complete circle has an angle of 2*pi radians. Multiply this by the radius and you have 2*pi*radius, which is the circumference of a circle (measured in units, not square units).
What else can I help you with?
How do you find the diameter when you only have the arc measure and length?
Suppose the angle of the arc is x radians and the length of the arc is a units. Then, if the radius of the circle is r units, a = rx or r = a/x So d = 2a/x units of length.
What is the length of the arc formed by central angle 2x?
If the angle is 2x radians then the length of the arc is 2x*r units where the radius of curvature is r units. If you measure the angle in degrees, then the length of the arc is pi*x*r/90 units.
What is the area of a sector of a circle that has a diameter of ten inches if the length of the arc is ten inches?
The area of a sector of a circle that has a diameter of ten inches if the length of the arc is ten inches is: 25 square units.
How many square units is the area of the square?
Take the length of a side (a square has all 4 sides same length) in the units, and square that number (multiply it by itself), then take the units as square units. Example: a square has a side length of 3 units, then the area = (3 units)2 = 9 units2.
Area of the square?
Length of Side*Length of Side (in square units).
Find the area of a sector of a circle with radius 12 and arc length 10pi?
The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.
How do you find the diameter when you only have the arc measure and length?
Suppose the angle of the arc is x radians and the length of the arc is a units. Then, if the radius of the circle is r units, a = rx or r = a/x So d = 2a/x units of length.
What is the length of the arc formed by central angle 2x?
If the angle is 2x radians then the length of the arc is 2x*r units where the radius of curvature is r units. If you measure the angle in degrees, then the length of the arc is pi*x*r/90 units.
What is the arc length of the minor arc of 120 degrees and the radius of 8?
Arc length = pi*r*theta/180 = 17.76 units of length.
What is the area of a sector of a circle that has a diameter of ten inches if the length of the arc is ten inches?
The area of a sector of a circle that has a diameter of ten inches if the length of the arc is ten inches is: 25 square units.
What is the arc length of the arc that contains 24 degrees and the circumference is 55 units?
24/360=arc length/55 arc length=55*24/360=11/3=3.66666666666666....
What is the area of a square with sides the length of six?
The area of a square of length m is m2 Accordingly, for a square of side length 6 length units = 62 square units. = 36 square units
What is the side length of a square with an area of 2 square units?
The side length of a square with an area of 2 square units is: 1.414 units.
What is the area of a square with a side length of 5 units?
The area of a square with a side length of 5 units is 25 square units.
How many square units is the area of the square?
Take the length of a side (a square has all 4 sides same length) in the units, and square that number (multiply it by itself), then take the units as square units. Example: a square has a side length of 3 units, then the area = (3 units)2 = 9 units2.
What is the measure of an arc on an angle that is 84 degrees?
84*r*pi/180 units of length where the radius is r units of length.
