Question

Q4
A chord AB of a circle with
centre o subtends an angle of
120° at the centre. If the radius
of the circle is 30 cm, find the
area of the minor segment APB.
(V3 = 1.7, T = 3.14)​

Answer 1

Answer:

Step-by-step explanation:

area of sector = theta/ 360 × πr^2

thus, 120/360 × 3.14 × 900 ..........….......since 30^ 2=900

thus,1/3 × 314× 9

thus,area = 314 × 3 cm^2

=942

thus the area of the sector is 942 sq.cm
