The radius of a circle with centre at O is 6 cm and the central angle of a sector is 40°. Find the area of the sector. |
6π cm2 5π cm2 4π cm2 8π cm2 |
4π cm2 |
Area of sector = \(\frac{ θ }{360° }\) × πr2 Area of the given sector = \(\frac{ 40° }{360° }\) × π × 62 = (\(\frac{1}{9}\) × π × 36) cm2 = 4π cm2 |
