AB=10+cm
we know that AC=BC=r
using Pythagorean theorem we have that
%28AB%29%5E2=2%28BC%29%5E2
%28BC%29%5E2=%2810%29%5E2%2F2
%28BC%29%5E2=100%2F2
%28BC%29%5E2=50
BC=sqrt%2850%29
BC=5sqrt%282%29
if a bowl is 2%2F5 filled with water, then find 1%2F5 of BC
BC%2F5=5sqrt%282%29+%2F5=sqrt%282%29
then, 2%2F5 will be 2sqrt%282%29
the depth of the water is 2sqrt%282%29cmor approximately 2.8cm

Formulation of this problem in the post is terrible.

How triangle ABC is logically or physically connected with the water in the bowl ?


How this problem is worded, it really scares and perplexes me . . .


It looks more like a horror movie than a Math problem . . .


The post by @MathLover1 is  INADEQUATE  and  INCORRECT  solution,
which must be ignored.
