what are "similar" circles? If you mean they have the same radius, then
ABC is equilateral, with side 14, circles have radius 7.
Area of ABC is 49/2 √3
Area of circular sectors included in ABC is
3 * 1/2 (40)(π/3) = 20π
Dunno what's shaded or not, but that should give you the numbers to work with.
the figure below shows 3 similar circles that just touch one another.A,Band C are the centres of the circles.If the perimeter of the triangle ABC is 42cm, what is the total area of the unshaded part of the 3 circles. (take pie = 22/7)
