Question

For 50 points
find minor sector and major sector of a circle of radius 21 cm and the angle subtended at the centre of a circle is 60 degree​

Answer 1

We will just apply the formula,

Area of minor sector :  πr²(center angle /360)

=22/7×21×21×60/360=66×21×1/6=231cm²

Similarly area of major sector =  πr²(center angle/360)

=22/7 ×21 × 21 × 300/360=66×21×5/6=231×5=1155cm².

Answer 2

Answer:

Area of major sector = 1155 cm^2 and minor sector = 231 cm^ 2
