Question

find the total surface area of cylinder whose height is 7 m and radius is 1.5m

Answer 1

Answer:

Step-by-step explanation:

tsa of cylinder = 2πr(r+h)

2 x 22/7 x 15/10(15/2+7)

2 x 22/7 x 15/2(15+14/2(lcm))

22/7 x 15(29/2)

22/7 x 15/1 x 29/2

4785/7 = 683.571428571

Answer 2

Answer:

Step-by-step explanation:total surface area of cylinder =(2*22/7*1.5*7)+ (2*22/7*1.5²)

=80.124
