A metal pipe is 63cm long. Inner diameter of a cross section is 6m and the outer diameter is 8cm find:-surface area of the base a , surface area of the base b , the outer curved surface area inner curved surface area total surface area

  • maths -

    area of base: pi(8^2-6^2) = 28pi
    outer area: 2pi*8*63 = 1008pi
    inner area: 2pi*6*63 = 756pi
