Someone help find surface area of a right rectangular prism
Bond [772]

Answer:

51 square units

Step-by-step explanation:

First you act like each side is it’s separate rectangle.

Then you would multiply 2 and 4 to get 8, the area of one of the sides. Then you would multiply 2 and 2.5 to get 5, the area of another side. Then 2.5 times 5 to get 12.5, the last side. Now sense every side has a side the same size of itself you would take each answer and multiply it by to to get 8x2=16, 5x2=10, and 12.5x2= 25. You would add together 16, 10, and 25 to get 51 square units, the surface area.

An aircraft on a reconnaissance mission takes off from its home base and flies 550 miles at a bearing of s 46° e to a location i
liubo4ka [24]

The  total distance it flies, rounded to the nearest mile is: d. 1,692 miles .

<h3>Total distance</h3>

First distance= 550 miles (given)

Second distance=483 miles (given)

Now let find the third distance

Let x represent the third distance

Hence:

x/sin79 = 550/sin55

x= 659.1

Now let calculate the total distance

Total distance=550+483+659.1

Total distance= 1692.1

Total distance= 1692 miles (rounded)

Therefore the correct option is d.

Find the radius of the circle below. Round your answer to the nearest tenth.
Butoxors [25]

Answer:

5.8 cm

Step-by-step explanation:

Area of the shaded sector of the circle = 31.2 cm²

Angle (θ) of the minor sector = 360 - 256 = 104°

Are of sector of a circle is given as, θ/360*πr²

Therefore:

\frac{104}{360}*3.142*r^2 = 31.2

0.29*3.142*r^2 = 31.2

0.91*r^2 = 31.2

Divide both sides by 0.91

\frac{0.91*r^2}{0.91} = \frac{31.2}{0.91}

r^2 = \frac{31.2}{0.91}

r^2 = 34.286

r = \sqrt{34.286}

r = 5.8 (nearest tenth)
