    Total surface area = 61.23 in ^2

    Step-by-step explanation:

    To find the total surface area of a cylinder, we use the formula

    T. S. A. = 2 π r h + 2 π r^ 2

    where r is the radius and h is the height

    We know the radius is 1.5 and the height is 5

    Substituting the values into the equation

    T. S. A. = 2 π (1.5) (5) + 2 π (1.5) ^2

    = 15 π + 4.5 π

    = 19.5 π

    Using 3.14 for π

    = 19.5 * (3.14)

    =61.23 in ^2
