Question

Find the surface area of the cylinder

Answer 1

Answer: 62.85 unit²

Step-by-step explanation: TSA of cylinder = 2pi r² + 2pi rh

= 2pi r(r + h)

= 44/7( 1+9) = 440/7 = 62.85 unit²

Answer 2

127.6 m²

Explanation:

To find the surface area of a cylinder we need to use this formula:

2πrh + 2πr² =

= (2*3.14*1*19) + (2*4.14*1*1) =

119.32 + 8.28 = 127.6m²
