Question

Three circles each of radius 3.5cm are drawn in such a way that each of them touches the other two. Find the area enclosed between these three circles. Pls answer this

Answer 1

hey buddy,
here is your ans..

firstly,
find tha side of a triangle formed
ie 3.5+3.5=7.0cm
now,
area of equilateral triangle = root 3/2 (side)^2 = root3/2 (7)^2 = root3*49/2

find the area of 3 sectors formed = theta/360*pi*r^2 =
theta = 60° ( all angles are of 60° in equilateral triangle)

after all the calculation

final step,

area of enclosed part = area of triangle - area of 3 sectors.

I think the calculation you have to do with yourself

I hope it will help you

Thank you..:-) :-)
