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

Answer:
see explanation
Step-by-step explanation:
This is an example of the Altitude - on - Hypotenuse theorem.
The altitude that is perpendicular to the hypotenuse of a right triangle.
The two triangles formed are similar to the given triangle and to each other.
x² = (smaller part) × (larger part) of main hypotenuse
x² = 6 + 19 = 114 ( square root both sides )
x ≈ 10.68 ( nearest hundredth )
---------------------------------------------
y² = ( smaller part) × (whole part) of main hypotenuse
y² = 6 × 25 = 150 ( square root both sides )
y ≈ 12.25 ( nearest hundredth )
--------------------------------------------
z² = ( larger part) × (whole part) of main diagonal
z² = 19 × 25 = 475 ( square root both sides )
z ≈ 21.79 ( nearest hundredth )
