    Given:

    A cylindrical container closed of both end has a radius of 7cm and height of 6cm.

    Explanation:

    A.) Find the total surface area of the container.

    • A = 2πrh + 2πr²
    • A = 2(3.14)(7)(6) + 2(3.14)(7 × 7)
    • A = 263.76 + 307.72
    • A = 571.48

    B.) Find the volume of the container.

    • V = πr²h
    • V = (3.14)(7×7)(6)
    • V = 923.16

    Not sure huhuness.

    Mark Brainliest please

    Answer: TSA = 572 cm^2
    Volume = 924 cm^3

    TSA of a cylinder = 2πr^2+2πrh

    = 2πr(r+h)

    = 2×22/7×7(7+6)

    = 44×13

    = 572 cm^2

    Volume of the container= V = πr^2 h

    = 22/7 * 7*7 * 6

    = 924 cm^3
