Question

In a circle with centre 0 and radius 5 cm, AB is a chord of length 5 cm. Find the area of the sector AOB. (Take n = 3.14)

Answer 1

Answer:

=13.08cm^2

Step-by-step explanation:

in the above information radius and chord are equal

so it forms an equilateral triangle

so the angle made by the chord at the centre is 60

so sector area = (60/360)*3.14*5*5

= (1/6)*(3.14)*25

=13.08cm^2
