Answer:

k = 13

Step-by-step explanation:

1. A straight angle is equal to 180 degrees, and a right angle is 90 degrees. With this information and the angles of (4k-7) and (3k+6), we can build an equation of:

$4k-7+90+3k+6=180$

2. (Solving)

Step 1: Combine like terms.

$4k - 7 + 90 + 3k + 6 = 180$
$(4k+3k) + (-7+90+6) = 180$
$7k + 89 = 180$

Step 2: Subtract 89 from both sides.

$7k + 89 - 89 = 180 - 89$
$7k = 91$

Step 3: Divide both sides by 7.

$\frac{7k}{7} = \frac{91}{7}$
$k = 13$

Help, I’m stuck. Thank you very much

If you notice, the container is really just two circles, with a diameter of 4 each, and a square with sides of 10.5.

now, if we just get the area of each circle, keeping in mind their radius is half of the diameter, namely r = 2, and get the area of the 10.5x10.5 square, sum them up, that'd be the surface area of the container.

$\bf \stackrel{\textit{2 circle's area}}{2(\pi r^2)}~~+~~\stackrel{\textit{area of the square}}{10.5\cdot 10.5}
\\\\\\
\stackrel{\textit{2 circle's area}}{2(\pi 2^2)}~~+~~\stackrel{\textit{area of the square}}{10.5\cdot 10.5}\implies 8\pi + 110.25$
