Find the area of the sector if the radius is 6 cm and with an angle of 60°.(a) 18.35 cm(b) 18.85 cm(c) 18.00 cm(d) 18.05 cmThe question was posed to me in a national level competition.Question is from Number of Tangents from a Point on the Circle topic in section Circles of Mathematics – Class 10

Answer» CORRECT choice is (b) 18.85 cm

To EXPLAIN: The area of the SECTOR = \(\FRAC {x^{\circ }}{360^{\circ }}\) × πr^2

= \(\frac {60^{\circ }}{360^{\circ }}\) x \(\frac {22}{7}\) × 6^2

= 18.85 cm
