Question

Find the area of minor segment of a circle with radius 12 cm and central angle 90°​

Answer 1

Step-by-step explanation:

Given the radius of a circle is 14 cm and a minor segment of the central angle is also 60

∘

.

We know that area of segment =πr

(

360

c

) (where c is the central angle of segment and r is a radius of the circle)

Then area of minor segment =
