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

How would the expression x^3+64 be rewritten using sum off cubes

Mamont248 [21]

$\bf \textit{difference of cubes}
\\ \quad \\
a^3+b^3 = (a+b)(a^2-ab+b^2)\qquad
(a+b)(a^2-ab+b^2)= a^3+b^3 \\ \quad \\
a^3-b^3 = (a-b)(a^2+ab+b^2)\qquad
(a-b)(a^2+ab+b^2)= a^3-b^3\\\\
-------------------------------\\\\
\boxed{64=4^3}\qquad x^3+64\implies x^3+4^3\implies (x+4)(x^2-x4+4^2)
\\\\\\
(x+4)(x^2-4x+16)$

PLEASE HELP ME ASAP 50 POINTS AND BRAINLIEST!!!!!!

Virty [35]

Answer:

The first shape is triangle; area of a triangle = 1/2*b*h

= 1/2*7*3

= 1/2*21

= 21/2

= 10.5

The second shape is rectangle; area of rectangle = l*b

= 7*3

= 21

Total area:

10.5+21

= 31.5
