Question

    Find the approximate volume of a right circular cone

    having diameter 14 cm and height 3cm.(Take pie = 3.14.)
    A 165 cm³ Correct Answer Incorrect Answer
    B 143 cm³ Correct Answer Incorrect Answer
    C 154 cm³ Correct Answer Incorrect Answer
    D 132 cm³ Correct Answer Incorrect Answer

    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
