Question

Find the volume of the cone. Round decimals nearest tenth. D = 12cm, h = 8 cm

  1. 3617.3 cm3
  2. 361.7 cm3
  3. 301.4 cm3
  4. 30.1 cm3

hintHint:

Volume of a cone = (1 third)πr2h

The correct answer is: 301.4 cm3


    We have given the dimensions of a cone
    Diameter = 12 cm
    Radius, r = 12 over 2 = 6 cm
    Height, h = 8 cm
    We have to find the volume of the given cone
    We know that
    Volume of a cone = (1 third)πr2h

    = (1 third)(3.14)(6 x 6) (8)

    = (1 third)(3.14) (36 x 8)

    = (1 third)(3.14)(288)

    = 904.32 over 3

    = 301.4 cm3
    Therefore correct option is c) 301.4 cm3.
