    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

    Why didn't we square the radius when working out circumference

    • @maths_monkey
      @maths_monkey  5 місяців тому

      The radius does not get squared in the circumference formula. Area = Pi x r squared. Circumference = 2 x Pi x r
