Question

If the radius of the circle is 10 cm what will be the arc length of a sector having Central angle 60 degree​

Answer 1

Answer:

15cm

Step-by-step explanation:

Arc length is given by:

A=rθ

Where A is arc length.

∴

A=(10) (1.5)

= 15cm

This makes sense, if you consider how we define a radian measurement.

If the radius of a unit circle (radius 1) describes an arc on the circumference equal to its length, then the angle subtended by this arc is defined as 1 radian.

So, if we have a radius of 10cm, and it describes an arc 1.5 times its length, then the length of the arc is 15cm.

Answer 2

Answer:

l=r*theta

where l= length of arc

Step-by-step explanation:

therefore l=10*π/3
