Area of the sheet used to make the tank = total surface area of the cylinder = 2
$\pi$ r(r+h) = 2 x 22/7 x 63 x 263 = 104148 sq. cm.

Total Area = 104106.097 cm²

Explanation:

Step 1:

We know that the total area of cylindrical tank is

TOTAL AREA = 2πR² + 2πRH units

where R =radius

H= Height

Step 2:

Radius = 63 cm

Height = 200 cm

Total area =
$(2*\pi * 63*63)+(2*\pi *200*63)$

Total area = 104106.097 cm²
