Answer:
Hii dear ,
# Answer - 1.5x10 ^ 4 mm ^ 2
# Given
Radius = 2cm
Height = 10cm
# Formula
Total surface area of cylinder is given by ,
Total surface area = 2n1r ( r + h )
Total surface area = 2x3.14x2x ( 2 + 10 )
Total surface area = 150.72 cm ^ 2
Total surface area = 150x100 = 1.5x10 ^ 4 mm ^ 2
Total surface area of the cylinder is 1.5x10 ^ 4 mm ^ 2 .
Hope this cleared your doubt .

r=2cm, h=10cm.
TSA = 2πr(r+h)
= 2×22/7 ×2(2+10)
= 88/7× 12
= 150.8cm² ans.
In mm:- 150.8cm = 150.8/10
= 15.08mm².
