Question:

Radius of a circle is 10 cm. Area of a sector of the sector is 100 cm2 . Find the area of its corresponding major sector. ( = 3.14 )

Answer:

Given radius of circle , r = 10cm
Area of minor sector , A = 100cm²
Area of circle = r² = 3.14×10² = 3.14×100 = 314cm²
Area of major sector = Area of circle – Area of minor sector
= 314-100
= 214cm²
Hence the area of the major sector is 214cm²
