Question

Help me find it pls i will give 10 pts

Answer 1

Answer:

703.7cm²

Step-by-step explanation:

Since we must not count the top and bottom 2cm,

- The height of the label is (20-2-2) = 20 - 4 = 16cm

- Finding the curved surface area of a cylinder: 2πrh

where r = radius and h = height.

- Since the diameter is 14cm, the radius is 14/2 = 7cm

- Substituting 'r=7' & 'h=16' into the curved surface area of a cylinder formula:

2π(7)(16)

= (14)(16)π

= 224π

= 703.716754404cm²

≈ 703.7cm²

Hope this helps and be sure to have a wonderful time ahead at Brainly! :D
