    Mam,why is the radius not squared in the circumference yet in the TSA is 1^2?

    • @maths_monkey
      @maths_monkey  Před 4 měsíci

      Circumference is like the perimeter, it is only squared when calculating area.

  • @Mr.Peanutbutter1
    @Mr.Peanutbutter1 Před 7 měsíci

    The TSA for a cylinder is 2(π x r²) + 2(l x b) I did it just as 2 x π x r² + l x b and we got different answers

    • @maths_monkey

      You would get different answers since these are different equations.
