Answer» Correct Answer - Option 1 : 66 Concept: For circle Area = \({\pi\over 4}× D^2\)
Circumference = π × D The ratio of area to diameter = \({Area\over Diameter}={\pi\over 4}× D \) where D is the diameter Calculation: Given: Circumference = 264 m, \(π = {22\over 7}\) we know that Circumference = π × D D = \({264\over \pi}=264×{7\over 22}\) m D = 84 m The ratio of area to diameter = \({Area\over Diameter}={\pi\over 4}× D \) The ratio of area to diameter = \({{22\over 7}\over 4}×84 \) The ratio of area to diameter = \({{22\over 7}\over 4}×84 = 66\) Hence the ratio of area to diameter is 66 m. |
