In Fig, a square OABC is incribed in a quadrant OPBQ. If OA = 20 cm, find the area of the shaded region `("Use"pi=3.14)`

in fig. find the area of the shaded region [ use pi = 3.14 ]

In Fig, OACB is a quadrant of a circle with centre O and radius 3.5 cm. If OD = 2 cm, find the area of the shaded region.

In the given fig OACB is a quadrnat of a circle with centre O and radius 3.5 cm . If OD = 2cm find the area of the shadded region .

In fig, arcs are drawn by taking vertices A, B and C of an equilateral triangle of side 10 cm, to intersect the sides BC, CA and AB at their respective mid-points D, E and F. Find the area of the shaded region. ("Use " pi = 3.14) .

AB and CD are two diameters of a circle perpendicular to each other and OD is the diameter of the smaller circle. If OA = 7 cm, find the area of the shaded region.

In the figure, Delta ABC is in the semi-circle, find the area of the shaded region given that AB = BC =4 cm ("use " pi= 3.14)

In Fig, OACB is a quadrant of a circle with centre O and radius 3.5 cm. If OD = 2 cm, find the area of the quadrant OACB
