1.	What is the ratio of the TSA of solid hemisphere to the square of its radius
Answer» {tex}{/tex}Let radius of the sphere = r\xa0Ratio =\xa0{tex}\\frac { \\text { Total surface area of hemisphere } } { \\text { Square of its radius } } = \\frac { 3 \\pi r ^ { 2 } } { r ^ { 2 } } = \\frac { 3 \\pi } { 1 }{/tex}{tex}\\therefore{/tex}\xa0Total surface area of hemisphere : Square of radius = {tex}3 \\pi : 1{/tex}
