Answer:
the total surface area of the rocket: 1978.2
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
The area of the cylinder is: 2*π*r*h+pi* (without the top part of it)
= 2*3.14*6*42 + 3.14*
= 1695.6
At the end, the total surface area of the rocket:
1695.6 + 282.6
= 1978.2
