cone

• the volume of a cone is 1/3 circulsr base area times the height
• volume - pi r squared height
• answer , given r - 12cm h - 30cm

  use formula - pi r squared height divided by 3

  = 3.14 x 12 x 12 x 30 divided by 3

  multiply radius first before the height then multiply by pi then divide by 3

  =21, 195 cm3 divided by 3

  = 7,065 cm 3
