find the surface area of a Cylindrical grain silo with hemispherical top
height=71
diamatere=62

  • math - ,

    So the radius of the top is 31 and the surface area of the hemisphere
    = (1/2)4pi(31)^2
    = 1922pi

    Surface area of cylinder
    = 2pi(31)(71) = 4402pi
    so the total surface area = 6324pi
