  1. Diameter=2r

    r=7

    L²=r²+h²

    L²=7²+24²=625

    L=√(625)=25

    You know l=25 ,r=7 and h=24

    Plug into the formula above and you done

    recall that TSA==πrl+πr²=πr(l+r)

  2. total I assume includes the base
    so
    pi r^2 + pi r L = pi r (r+L)
    where L is the slant height =sqrt(r^2+h^2)
    here r = 7 cm and h = 24 cm
    L= sqrt( 49 + 576) = sqrt (625) = 25 that is handy :)
    so
    pi r (r+L) = pi (7)(7+25)
