Question
Find the approximate volume of a right circular cone
having diameter 14 cm and height 3cm.(Take pie = 3.14.)Solution
Radius of the cone = Diameter/2 Radius of the cone = (14/2) = 7 cm Height of the cone = 3 cm Volume of the cone = (1/3) x π x r2 x height = (1/3) x 3.14 x 7 x 7 x 3 The volume of the cone is approximately 153.86 cm³. or ~ ` ` 154 cm3
