= 1.4cm and height
=5cm.​

Answer 1

Answer:

56.32

Step-by-step explanation:

r=1.4cm,h=5

tsa of cylinder is 2πr(r+h)

2x22/7x1.4(1.4+5)

8.8(6.4)

56.32

and please thank my answer

Answer 2

Step-by-step explanation:

Total Surface Area of a Cylinder = 2πr ( r+h). ( here; r= radius & h = height )

= {2 × 3.1416× 1.4×( 1.4+5) } cm

= ( 2×3.1416×1.4×6.4) cm

= 56.297472 cm

Then , the final answer is 56.297472 cm
