Anuta_ua [19.1K]

Answer:

$(2,\infty)$

Step-by-step explanation:

After x=2, we see that the change in y over the change in x is positive since both variables increase with each other, so $(2,\infty)$ is where the function is increasing.

A small cylindrical has a diameter of 18mm and a height 12mm. Determine the minimum surface area of a box that can hold a row of

dimaraw [331]

Answer:

The surface are of a box = 1186.92 mm²

Step-by-step explanation:

Given in question as :

Diameter of cylinder = 18 mm

The height of cylinder = 12 mm

The surface area of cylinder = ( 2× $\pi$ ×r×h) + (2× $\pi$ ×r²)

where R is the radius , R = $\frac{Diameter}{2}$ = $\frac{18}{2}$

Or Radius r = 9 mm

Or, The surface area of cylinder= ( 2× $\pi$ ×9×12) + 2× $\pi$ ×(9)²)

Or , The surface area of cylinder=(678.24) + (508.68)

Or ,The surface area of cylinder= 1186.92 mm²

Hence the surface are of a box = 1186.92 mm² Answer
