The total air of the solid is 458 cm². What is the total height of the solid

9514 1404 393

  27.1 cm

Step-by-step explanation:

The area of the solid is the lateral area of the cylinder plus the total area of the cone of unknown height. In terms of the cone's slant height (s), the total area of the solid is ...

  A = πdh +πr(r +s) . . . . diameter d, height h, radius r, slant height s

  458 = π(6·18 +3(3+s))

  145.786 = (108 +9 +3s)

  28.786 = 3s

  s = 9.595

Then the height of the cone is found from the Pythagorean theorem as ...

  √(s² -3²) ≈ 9.1 . . . . cm

The total height of the solid is about ...

  18 cm +9.1 cm = 27.1 cm

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.
