Question

Radius 3cm AOB-60 degree. Find the perimeter of AOB

Answer 1

Answer:

perimeter = 3.14

Step-by-step explanation:

We have

r=3cm

Angle AOB=60degree

Then......

We can use the formula..i.e..

Perimeter = Given angle÷360×circumference of the circle i.e 2πr

Now,

Given angle is 60 degree

and radius is 3cm

So,

60÷360×2×π×3

=1÷6×2×3.14×3

= 6×3.14÷6

= 3.14
