Question

Answer

(a) Area of the full circle =  3.14 * 10² = 314 cm²

Area of the figure OPQRS = Area of full circle  – shaded area

= 314 –  98  = 216 cm²

(b) Similary , perimeter of OPQRS = Perimeter of full circle – perimeter of curve part of shaded area + 2 * radius

= 2 * 3.14 * 10 – (39- 2 * 10 ) + 2 * 10 = 63.8cm
