In the given figure, AB = 36 cm and M is the midpoint of AB. Semicircles are drawn on AB, AM and MB as diameters. A circle with centre C touches all the three circles. Find the area of shaded region. [Hint : Take O as the centre of semicircle on diameter AM. Take the radius of the circle with centre C as r. Then , OC = (9 + r)cm, OM = 9 cm and CM = (18-r) cm. Now, use Pythagoras theorem and find r = 6 cm.]

In the given figure AB = 8 cm, M is the mid-point of AB. Semi-circles are drawn on Ab with AM and MB as a diameters. A circle with centre 'O' touches all three semi-circles as shown. Prove that radius of this circle is (1)/(6) AB.

In the figure, AB is a diameter of the circle with centre O and OA = 7cm. Find the area of the shaded region

In the figure,AB is a diameter of the circle with centre O and OA=7cm. Find the area of the shaded region

In the figure semicircles are drawn with PQ, PB and BQ as diameter. PB = BQ = 21 cm . A circle with centre O is drawn to touch all the three semicircles. Find its radius and also find the shaded region.
