  1. Answer:

    Given,

    Slant height of cone is l=21 m.

    Diameter of its base is d=24 m.

    hence, radius of its base is r=

    2

    d

    =12 m.

    Now, the total surface area of cone is given by

    S=πrl+πr

    2

    S=π(rl+r

    2

    )

    S=π(12×21+12

    2

    )

    S=π(252+144)

    S=

    7

    22

    ×396

    hence, S=1244.57 m

    Step-by-step explanation:

    hope it helps please

    mark as brilliant
