Question

if the radius of the sphere is 14 cm if the,radius id increased by 50% find by how much volume is increased

Answer 1

volume of spehere=4/3*$\pi$*R³
CASE 1:
radius=14 cm
volume=1044cm³

CASE 2:
radius=14+50% of 14
          =14+7=21 cm
volume with radius 21 =38772cm³
change in volume=38772-1044 =37728cm³

Answer 2

volume of spehere=4/3**R³
CASE 1:
radius=14 cm
volume=1044cm³

CASE 2:
radius=14+50% of 14
          =14+7=21 cm
volume with radius 21 =38772cm³
change in volume=38772-1044 =37728cm³
