A Rope Can Make 70 Rounds Of The Circumference Of A Cylinder Whose Radius Of The Base Is 14cm. How Many Times Can It Go Round A Cylinder Having Radius 20 Cm? |
|
Answer» Let the required number of rounds be X More RADIUS, less rounds(Indirect PROPORTION) Hence we can write as (radius) 14 : 20 :: xx : 70 ⇒14×70=20x ⇒14×7=2x ⇒x=7×7=49. Let the required number of rounds be x More radius, less rounds(Indirect proportion) Hence we can write as (radius) 14 : 20 :: xx : 70 ⇒14×70=20x ⇒14×7=2x ⇒x=7×7=49. |
