Answer:
Lateral Surface Area: 56 in²
Total Surface Area: 81 in²
Step-by-step explanation:
To find the lateral surface area, all we need to do is find the surface area for one of the lateral faces and then multiply it by 4.
Now the area of all the lateral faces:
14*4=56
The total surface area is the lateral area plus the base.
56+(5*5)=56+25=81
The radius of a circle is always the square root of the number on the right. The other two numbers describe the center.
Center: (11,-15) Opposite of what's in the brackets.
Radius: sqrt(144) = 12

Satisfies Pythagoras Theorem, therefore triangle ABC is right angles triangle.
Answer:
Perpendicular
Step-by-step explanation:
Put all the points on a graph.
Parallel means that the lines that have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect.
On the graph we made we can see that the lines will have to intersect because the points are in positions that no matter which points we chose to connect together, they would intersect with the other line.
258 cubic inches
Since the boxes are kind of on their own—>
First box: 7*2*12 = 168
Second box: 5*2*9=90
168+90 = 258
