Seven circles, each with radius 1, overlap to form the composite figure shown below. Find the area of shaded region?
2π
We can clearly see 6 "petals" (inner) and 6 "funnels" (outer). Now,
So the area is 2πr^2 = 2π
7 non-overlapping unit circles are inscribed inside a large circle as shown below. Find the area of the shaded region?
Two congruent circles of radius 5 cm are drawn in such a way that one is 1 cm below the other . Find the area of red coloured region?
Find the area of the blue shaded region in this 14x7 rectangle, with two semicircles of radius 7 drawn.
A circle with radius 1 is divided into 12 congruent regions, as shown below. What is the perimeter of a single region?
Two circles with the same radius overlap each other. Their circumferences cross each other's center. How much of the area of either circle in percentage is the overlapped area?
