Question

how many square meters of tin sheets is required to make a closed cylindrical tank of height 2m and base diameter is 1.4m

Answer 1

TSA of cylinder = 2πr(r+h)

TSA = 2*22/7*0.7(0.7+2)

TSA = 4.4*2.7

TSA = 11.88 m square

I hope it will help u

Answer 2

TSA of cylinder = 2pie r(r+h)

= 2×22/7×1.4/2(0.7+2)

= 44×0.1×2.7

=11.88 m

Thanks for the opportunity and I think this helps you a lot
