Total height =30×3 =90 cm.
TSA of cylinder = π×r×r×h= (22÷7)×14×14×90
=55440 cubic cm.

Answer:radius = 14 cm
We know that cylinder is obtained when circles of same radius are arrnged obe after another.
Therefore the figure so obtained is a cylinder.
Tsa of cylinder = 2pie r ×(r+h)
Height of cylinder= 30×3=90cm
=2×22/7×14(14+90)
=9152 squareunits cm
