Calculate the volume and curved surface area of a cone 14cm in base diameter and 24cm high

  • Maths -

    radius of base = 7 cm,
    let the slant height be s
    s^2 = 24^2 + 7^2
    s = 25

    V=(1/3)πr^2h = (1/3π)(49)(24) = 392π cm^3

    SA = πrs = π(7)(24) = 392π cm^2

    You didn't say if you want the circular base included, if so, add 49π cm^2

  • Maths -

    Vol=1/3 pie r^2h
