To find radius just divide diameter by 2
So the answer will be
6 divide 2 = 3mm
Answer:
4d x 5e is it simplified
Step-by-step explanation:
Change (3d - 7e) x (2e + d) to a simpler equation like (3d + d) x (-7e + 2e)
Combine the 2 and you'd get 4d x -5e. That's the most I can simplify it to for now. Hope this helps! The question wasn't clear

Answer:
Explanation:
The figure attached shows sketches the situation described.
You have two right triangles.
For the right triangle with the plane on the position A, you can write:
⇒ H = (800 + x) tan(20º)
For the right triangle with the plane on the position B, you can write:
⇒ H = x tan(21.4º)
To solve, equal both equations:
- x tan(21.4º) = (800 + x) tan(20º)
- x tan(21.4º) = 800 tan(20º) + x tan(20º)
- x = 800 tan(20º) / ( tan(21.4º) - tan(20º) )
Substitute in the equation H = x tan(21.4º)
- H = 10,426.899856 × tan(21.4º) = 4,086 ft
Rounding to one signficant figure that is 4,000 ft.
