Step-by-step explanation:

Given:-

The radius of the outer and inner radii of two circles are 6 cm and 2 cm respectively.

To find:-

Find the area between the two given circles

Solution:-

Radius of the outer circle (R)=6cm

Area of a circle whose radius is R units =

πR² sq.units

=>π(6)² sq.cm

=>36π sq.cm

Area of the outer circle = 36π sq.cm------(1)

Radius of the inner circle (r)=2 cm

Area of a circle whose radius is "r" units =

πr² sq.units

=>π(2)² sq.cm

=>4π sq.cm

Area of the inner circle = 4π sq.cm -------(2)

Area between the two circles

= Area of Outer circle - Area of inner circle

=>(1)-(2)

=>36π -4π

=>32π sq.cm

or

=>32×(22/7) sq.cm

=>(32×22)/7 sq.cm

=>704/7 sq.cm

=>100.57 sq.cm(approximately)

(or)

Radius of the outer circle (R)=6cm

Radius of the inner circle (r)=2 cm

Area between two circles = Area of the circular path = Area of the ring = π(R²-r²) sq.units

=>π(6²-2²) sq.cm

=>π(36-4) sq.cm

=>π(32) sq.cm

=>32π sq.cm

Or

=>32(22/7) sq.cm

=>(32×22)/7 sq.cm

=>704/7 sq.cm

=>100.57 sq.cm(approximately)

Answer:-

Area between the two circles =

32π sq.cm (or) 100.57 sq.cm

Used formula:-

  • Area of a circle of radius "r" units then

πr² sq.units

  • Area of the ring =π(R²-r²) sq.units

Where R is the outer radius and r is the inner radius of the circle.
