# In a circle of ra

Given radius of circle = R = 10.5 cm

Let the area of major sector be ‘A1’ and that of minor sector be ‘A2

We know, Area of circle = Area of major sector + Area of minor sector

Area of circle = A1 + A2

We also know, Area of circle = πR2

Where R = radius of circle, put value of area of circle in equation 2.

(taking 5 as L.C.M on R.H.S)

= 288.75 cm2

The area of major sector is 288.75 cm2.
