Length of an Arc

Length of arc of a sector is______

In the circle shown in the figure, the length of the arc ACB is 3 times the length of the arc AB. What is the length of the line segment AB ?

Length of the arc of a quadrant of a circle of radius 'r' is

There are two circle . The length of arc make angle at the centre 60^(@) and 75^(@) . If the length of arc is same then find the ratio of their radius.

In the given figure, O is the centre of the circle and the length of arc AB is twice the length of arc BC. if angleAOB =100^(@) find angleBOC

Length of the arc of circle with radius 5 cm and angle at centre is 15^@ ...........cm.

What is the area of the sector of a circle whose radius r and length of the arc is l.

If the angle of a sector is 30^(@) and the radius of the sector is 21 cm, then length of the arc of the sector is ______.

If the angle of a sector is 45^(@) and the radius of the sector is 28 cm then the length of the arc is _________.
