Here, r= 14 cm and {tex}\\theta = \\frac { 90 ^ { \\circ } } { 3 } = 30 ^ { \\circ }{/tex}{tex}\\therefore{/tex}Area swept = {tex}\\frac { \\theta } { 360 ^ { \\circ } } \\times \\pi r ^ { 2 }{/tex}={tex}\\frac { 30 ^ { \\circ } } { 360 ^ { \\circ } } \\times \\frac { 22 } { 7 } \\times 14 \\times 14{/tex}= {tex}\\frac { 154 } { 3 }{/tex}\xa0cm2
