Question

A circle of radius 5 cm is cut from circle of radius 6 cm find the remaining area

Answer 1

r1 = 5cm

r2 = 6cm

Area of circle with radius r2 = π r2^2

π6×6

= 36π cm^2

Area of circle with radius r1 = π r1^2

= π 5×5

=25π cm^2

Area of remaining portion = 36π - 25π

= 11π

= 11× 22/7

= 34.5714286 cm^2

Hence area of remaining circle = 34.5714286 cm^2

Answer 2

Answer:

The remaining area is 34.54 centimetres²

Step-by-step explanation:



Given

There are two circles

Radius of circle 1 = 5 centimetres

Radius of circle 2 = 6 centimetres

If the 1'st circle is cut from 2'nd circle then

Remaining area = area of circle 2 - area of circle 1

Area of circle = πr²        (π = 3.14)

Area of circle 1 = 3.14×5×5

Area of circle 1 = 78.5cm²

Area of circle 2 = 3.14×6×6

Area of circle 2 = 113.04 cm²

Remaining area = 113.04 - 78. 5

Remaining area = 34.54 centimetres²
