Four equal circle

Class 10th RD Sharma - Mathematics 15. Areas Related to Circles

Answer :

Radius of each circle = a meter

If we join the centre of each circle it makes a square of side = 2a

Area of square = (2a)² = 4a²m²

Area of each quadrant of circle =

Area of 4 quadrants =

So,

Area between circles = 4a² – πa²
