Question

29. In figure OACB is a quadrant of a circle with centre O and radius 3.5cm. If OD is 2cm, Find
the area of O quadrant OACB (ii) Shaded region.​

Answer 1

Answer:

Step-by-step explanation:

1) Area of Oquadrant =1/4πr²

                                =1/4π*(3.5)²

                                 =9.625 cm²

2) Shaded region = OACB- area of ΔBOD

                             = 9.625-3.5

                             =6.125 cm²
