Total surface area = 1936 sq. Cm
Radius = 7 cm
Height = ?
Total surface area of cylinder =
2×22/7.r (r+h) = 1936
44(7+h) =1936
308+44h=1936
44h = 1936-308
44h =1628
h=1628/44
h= 37 cm Answer.

Answer :
The total surface area of cylinder is 1470.85 cm²
Step-by-step explanation :
Radius = 9 cm
Height = 17 cm
Total surface area of cylinder = 2 π r ( h + r )
⇒ TSA = 2 π r ( h + r )
= 2 × 22 / 7 × 9 ( 17 + 9 )
= 44 / 7 × 9 × 26
= 1470. 85 cm²
Hence, the total surface area of cylinder is 1470.85 cm²
