Answer :

Find the perimeter of a square which circumscribes a circle of radius a cm.

Hide | Show

Answer :

Side of the square = 2  radius of circle = 2a cm

Then, Perimeter of the square = (4  2a) = 8a cm

Answer :

Area of shaded region = 2(Area of square) – 4(Area of semicircle) = 2 × 196 – 308 = 392 – 308 = 84 cm2

In Figure, arcs are drawn by taking vertices A, B and C of an equilateral triangle ABC of side 14 cm as centres to intersect the sides BC, CA and AB at BZ their respective mid-points D, E and F. Find the area of the shaded region. [Use π = 22/7  and  √3 = 1.73] (2011D)
