Since you are dealing with hypotenuse and opposites, you need to use sine.

sin = (opposite)/(hypotenuse)

sin(60) = (opposite)/20
sin(60) * 20 = 17.3

The length of the opposite side is approximately 17.3 centimeters

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
