Find the surface area of the regular hexagonal prism. Round your answer to the nearest hundredth.

1 answer:

6 0

A single rectangle has the area of (11 mm)(8 mm) = 88 mm²
So the lateral areas which are the total number of rectangles will be 6*(88 mm²) = 528 mm²
Just recall the formula of the regular polygon, given the side of that polygon.
This hexagon has the area of (1/4)*(6)*(8²)*cot(180°/6) = 166.28 mm²
There are two bases; so 2*(166.28 mm²) = 332.55 mm²

Hence, the surface area is lateral areas + base areas:
528 mm² + 332.55 mm² = 860.55 mm² (ANSWER: d)

tigry1 [53]

Answer:

Neptune has 2 more than 6 times the number of moons on mars

Explanation:

neptune = 6m+2

mars has 'm' moons

pluto has one more than twice that of mars, = 2m+1

neptune is one less than thrice of pluto

= 3(2m+1) -1

= 6m+3 -1

= 6m+2

Hello, happy Friday, I am just here with some geometry questions.

Hatshy [7]

Answer:

Step-by-step explanation:

So far, we know that:

∠D = ∠J.

And that:

DE:JK = 14:7 = 2:1

So, to prove that ΔDEF ~ ΔJKL by SAS, DF must be similar to JL, as those are the sides between the angle.

So:

DF:JL = 2:1.

Our answer is B.
