The three lengths are 3x, 6x, 8x.
The perimeter of a triangle is the sum of all lengths:
3x + 6x + 8x = 520.
Solving for x,
17x = 520
x = 30.59 cm
So the three lengths are
3(30.59) = 91.77 cm
6(30.59) = 183.54 cm
8(30.59) = 244.72 cm
Answer:
Error in the sphere's surface: 29
and relative error in surface measure: 0.011
Error in the sphere's volume: 205
and relative error in the volume measure: 0.017
Step-by-step explanation:
(a)
The measured length (l) of the circumference is 90 cm with an error of 0.5 cm, that is:

and with regards to the error:

then when we use the formula for the sphere's surface, we get:

Then the relative error in the surface is:

(b)
Use the formula for the volume of the sphere:

Then the relative error in the volume is:

Answer:
No it does not
