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​

Answer 1

Answer:

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,

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

Answer 2

Answer:

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 = 0/36° × πr²

20 = 60/360 ×πr²

20= 1/6 ×πr²

20×6 = πr²

120=πr²

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