Q.2 (A)(1) The radius of a circle with centre ‘P’ is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (π = 3.14)
[Figure: circle with centre P, chord AB, ∠APB = 90º, X on minor arc AB.]
Activity :
r = 10 cm, θ = 90º, π = 3.14.
A(P–AXB) = \(\dfrac{\theta}{360}\) × ____
= \(\dfrac{\text{____}}{360}\) × 3.14 × 102
= \(\dfrac{1}{4}\) × ____
A(P–AXB) = ____ sq. cm.
