Answer:

the total surface area of the rocket: 1978.2  m^{2}  

Step-by-step explanation:

Given that :

  • A rocket in the shape of a cone
  • The aslant height: 15m
  • The base diameter: 12m <=.> Radius: 6m
  • The height: 42

So the surface area of a a cone with about the base area because it is attached to a cylinder:

= π*r*l = 3.14*6*15 = 282.6 m^{2}

The area of the cylinder is: 2*π*r*h+pi*r^{2} (without the top part of it)

= 2*3.14*6*42 + 3.14*6^{2}

= 1695.6 m^{2}  

At the end, the total surface area of the rocket:

1695.6 m^{2}  + 282.6 m^{2} = 1978.2  m^{2}

The length of the red line segment is 8 and the length of the blue line segment is 4. How long is the major axis of the eclipse?
liraira [26]

The major axis of the eclipse is 12 units long

The given parameters can be represented as:

Red = 8

Blue = 4

See attachment for illustration

To solve this question, we make use of the following theorem

The distance between a point and the foci sums up to the major axis

This translates to:

Major\ axis = Red + Blue

Major\ axis = 8 + 4

Major\ axis = 12
