    Slant height is 6.15in

    Step-by-step explanation:

    Surface area of a come is expressed as πr²+πrl

    r is the base radius of the cone

    l is the slant height

    Given surface area = 175in²

    radius = 5in

    l = ?

    Substituting the given values in the formula to get l we have:

    175 = 5²π+5πl

    175 = 25π+5πl

    175 = 25 (3.14) + 15.7l

    175 = 78.5 + 15.7l

    15.7l = 175-78.5

    15.7l = 96.5

    l = 96.5/15.7

    l = 6.15in
