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.
