Question

if the sector of a circle has an angle 60 degree at the centre and its area 20 CM square then find the area of the same circle.
please answer​

Answer 1

Answer:

The area of same circle is 120 sq.cm

Step-by-step explanation:

Since we have given that

Angle of sector = 60°

Area of sector = 20 sq.cm

So , we need to find the area of same circle

So , it becomes ,

Area of sector = 0/360°×πr^2

20 = 60/360×πr^2

20 = 1/6×πr^2

20×6 = πr^2

120 = πr^2

Hence , the area of same circle is 120 sq.cm
