Ac And Bd Are Two Perpendicular Diameters Of Circle With Centre O

AC and BD are two perpendicular diameters of a circle with centre O. If AC = 16 cm, calculate the area … of the shaded part.(Take π…

Answers:

Given radius of circle is 8 cm.

Ar. Of shaded part = 1/2πr2 = ½ × 3.14 × 82

= 100.48 cm2

Perimeter of the shaded part

= πr + 4r

= 3.14 × 8 + 4 × 8

= 25.12 + 32

= 57.12 cm
