Answer 2

Answer:

Step-by-step explanation:

fIrst find the radius of small circle which is

Pi*r*r=pi

r=1

let centre is o

so oc =1 and AB=2 (diameter)

c is centre of another circle

jOin co

Oc=1 (above) and ao=1

(As line from centre bisect a chord perpendicular)

So ac=sq root(ao^2+oc^2)=sq root(1+1)=sq root (2)

Radius of big circle is sq root (2)

Area=pi*2=2pi

Now u got area of 2 circle

FInd the area urself
