    Answer:

    572.52 cm square

    Step-by-step explanation:

    here we have a closed cylinder.

    so we can divide it in two parts

    1) one open cylinder

    2) two circle that close the cylinder (both have same area)

    area of surface are of cylinder = 2 * pie * r * h

    = 2 * 3.14 * 7 * 10

    = 439.6 cm square

    area of circle that close the cylinder = 2 * pie * r

    = 2 * 3.14 * 7

    = 43.96 cm square

    now we have two circles so multiply it by 2 = 2 * 43.96

    =87.92 cm square

    now total surface area is add them all

    = 439.6 + 87.92 = 572.52 cm square

    Hope it helps

    Answer:

    diameter = 14cm

    radius = 14/2 = 7cm

    height = 10cm

    total surface area = 2πr(r +h)

                                   = 2×22/7×7(7+10)

                                    = 44×70

                                   = 3080cm²
