1.	A hemisphere has it\'s volume and surface area numerically equal . What would be it\'s diameter ?
Answer» Let radius of the\xa0hemisphere\xa0be r.According to the question,Volume of hemisphere\xa0= Surface area\xa0of hemisphere{tex}\\frac { 2 } { 3 } \\pi r ^ { 3 } = 3 \\pi r ^ { 2 }{/tex}{tex}r = \\frac { 9 } { 2 }{/tex}unitsDiameter of the hemisphere = 2( radius of the hemisphere){tex}\\therefore \\quad \\text { diameter } = \\frac { 9 } { 2 } \\times 2 = 9{/tex}
