Answer 2

Given Question

Total surface area of a cylinder of radius 0.7 m diameter and 1.0 m height is ?

According To The Question

Total surface area of a cylinder = 2 π r ( h + r )

TSA of a cylinder = 2 × 22/7 × 0.7 ( 1.0 + 0.7 )

TSA of a cylinder = 44/7 × 0.7 × 1.7

TSA of a cylinder = 44/7 × 1.19

TSA of a cylinder = 52.36/7

TSA of a cylinder = 7.48

Hence, TSA of a Given cylinder is 7.48 m.

Note :- There is no option to prove that TSA of a Given cylinder is 7.48 m. So, we should mark at none of these.
