The length of ——ab (the minor arc) is 40 cm. What is the circumference of circle c inside angle is 60 degrees?
s = 2 π r (θ/360°), C = πr^2
40cm = 2πr(1/6)
(40*6)/2π = r
r = 38.1972cm
C = π*(38.1972)^2
C = 4,583.66 cm

What is circumference?
The circumference of an object - particularly a circle - is the distance around the outside of it.
What is the arc in a circle that is 90 degrees?
To find the arc length, you also need to know the radius (or diameter) of the arc. The arc length is then found by finding the circumference of the full circle (2xPIxradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
What is the diameter circumference?
Diameter is the length of a straight line passing through the center of a circle or sphere and connecting two points on the circumference of the circle or the surface of the sphere. Circumference is the length of the closed curve of a circle.
If the arc on a particular circle has an arc length of 12 inches and the circumference of the circle is 48 inches what is the angle measure of the arc?
The angle measure is: 90.01 degrees
What is a circumference in math?
The length of the edge of a circle.
