Question

Find the circumference of a circle whose diameter is
m 14 cm
a) 35 cm
(1) 10.5 m
Find the radius of a circle whose circumference is 176 cm​

Answer 1

Answer:

Exterior angle = 22°

Number of sides = sum of exterior angles/ exterior angle

⇒ Number of sides = 360/22 = 16.36

No, we can’t have a regular polygon with each exterior angle as 22° as it is not divisor of 360.
