<span>assume z = ax for simplicity
z(z) = a(ax) = a^2x
let a^2x = 1/16x and solve for a </span>

Answer:
Radius, r, is 3.75
Step-by-step explanation:
From the given diagram,
AB = 9
AC = 6 + r
BC = r
Thus applying the Pythagoras theorem, we have;
= +
= +
36 + 12r + = 81 +
collecting like terms,
12r = 81 - 36
12r = 45
r =
= 3.75
r = 3.75
The radius is 3.75.
