The arc length of a circle is, 2.355 cm
Step-by-step explanation:
Use the fact that the length of an arc intercepted by an angle is proportional to the radius.
Let l be the length of an arc and r be the radius of the circle.
then;
lxr
then;
l=r0 [1]
It is also given: r = 3 cm and 0=pie/4
Substitute the given values in [1] we have;
Use pie=3.14
1=3*pie/4=3*3.14/4=2.355cm
Therefore, the arc length of a circle is, 2.355 cm
