Sort by:

Three circles having radius 1cm so by joining there centers we get equilateral triangle of 2cm so centre of circumcircle is 2sqrt3/3 distance from smaller circles centre. So radius of circumcircle=(1+2sqrt3/3) and hence area =pi*(7+4sqrt3/3) · 1 year, 11 months ago

Pi*(7+4sqt3)/3 · 1 year, 11 months ago

Pi*(7+4√3)/3 · 1 year, 11 months ago
