Question

length of arc of a sector angle 45 degree of circle of radius 14 cm is​

Answer 1

Answer:

The length of arc of a sector angle 45 degree of circle of radius 14 cm is​ 11 cm.

Step-by-step explanation:

Circumference of a circle is given by:

Circumference = πD whereby, D = the diameter of the circle.

In this case, we need to get the length of the arc.

Given the sector angle as Ф, the length of the arc is given by:

Ф/360 × πD

Now, D = 2r = 2 × 14 cm = 28 cm

Doing the substitution we have:

45/360 × 28 × 22/7 = 11 cm

The length of the arc is therefore 11 cm.
