Question

The side of a square is 10cm. Find the area between inscribed and circumscribed circles of the square. Following picture is given:-
(Tell me the area between both circles, please!!!!!!!)

Answer 1

radius of small circle=10/2=5

radius of big circle=√2side=10√2

ar between...square=ar of big circle - ar of small circle

Φ\360πR^2 - Φ\360πr^2

Φ\360π(R^2 - r^2)

90/360π{[10√2]2 - [5]2}

1/4π{200 - 25}

1/4π{175}

275/2cm^2

137.5cm^2
