Question:Find the area between two circles of radii 4 cm and 3 cm . given that the smaller circle lies entirely within the larger. 

Answer Area of the bigger circle =`pi(4)^2 cm^2` =16`pi cm^2`. Area of the smaller circle=`pi(3)^2``cm^2`= 9`pi cm^2` . Area between the circle = (16`pi`- 9`pi`) `cm^2`= 7`pi cm^2`. = 7`xx 22/7 cm^2` = 22 `cm^2`
