，球体体积增加的百分比

原文:https://www . geesforgeks . org/如果半径增加给定的百分比，球体体积增加的百分比/

这里给定的是一个球体，它的半径增加了给定的百分比。任务是找出球体体积增加的百分比。 例:

Input: x = 10
Output: 33.1%

Input: x = 50
Output: 237.5%

接近 :

  • 让，球体的半径= a
  • 给定百分比增加= x%
  • 增加前的体积= 4/3*πa^3
  • 增加后的新半径= a + ax/100
  • 所以，新卷= 4/3*π(a^3+(ax/100)^3+3a^3x/100+3a^3x^2/10000)
  • 成交量变化=4/3*π((ax/100)^3+3a^3x/100+3a^3x^2/10000)
  • 成交量增长百分比=(4/3π((ax/100)^3+3a^3x/100+3a^3x^2/10000)/4/3πa^3)* 100 = x^3/10000+3x+3x^2/100

         << " volume of the sphere is "
         << pow(x, 3) / 10000 + 3 * x
                + (3 * pow(x, 2)) / 100
