A. the first one will give you a perpendicular line to BA
Answer:

Step-by-step explanation:
Given that,
The radius of the sphere, r = 8 mm
We need to find the volume of the sphere. The formula for the volume of a sphere is given by :

Put all the values,

So, the volume of the sphere is equal to
.
The first to find the length of each side, we have to find the value of x :

Answer:
Option (4)
Step-by-step explanation:
If ΔLMN is similar to ΔQRS,
Their corresponding sides will be proportional.


But it's not true.
Therefore, the given triangles ΔLMN and ΔQRS are not similar.
Option (4) will be the answer.
