Question

2. (1) A chord of circle of radius 14 cm subtends a
right angle at the centre. What is the area of
the minor sector.
(ii) A chord of circle of radius 14 cm subtends an
angle 60° at the centre. Find the area of the
major sector​

Answer 1

Answer:

i) If the chord subtends a right angle at the centre, it means that the minor sector is a quadrant i.e. one-fourth of a circle…

Therefore, the area of the minor sector= 1/4 x Area of the circle with given radius

=1/4 x 22/7 x 14 x 14 (Since area of circle= pi x radius x radius; pi= 22/7)

=154 square units
