✯Question✯

  • If the radius of a sphere becomes 3 times of a previous radius then what percentage of its volume will be increased by how many times?

✬Given✬

  • Radius of sphere = 3( previous radius of sphere )

✭To find✭

  • Percent of the increased volume ( new volume )
  • To find the new volume would increase by how many times the original volume

✵Solution✵

  • Volume of sphere =  ⁴⁄₃ πr³
  • r = 3r ( radius becomes 3 times the original volume )
  • Substitute in ⁴⁄₃πr³
  • ⁴⁄₃π(3r)³
  • 27 × ⁴⁄₃πr³

✶The new volume is increased by 27times the original volume✶

✬The percentage of increase volume is 27%✬
