In the figure, square wxyz has a diagonal of 12 units. point a is a midpoint of segment wx, segment ab is perpendicular to segment ac and ab=ac. what is the length of segment bc?

BC= 18 units .

Explanation:

Since we have given that

Diagonal of square WXYZ is given by

As we know the  formula of "Diagonal of square",

Since 'A' is the midpoint of WX so,

Length of AX=YE is given by

Since AB=AC and ΔABC is right angled triangle , so,

So, In ΔCEY,

in ΔXYB,

So,

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
