Answer:
radius = 6.5
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
x² + y² = 42.25 ← is in this form
with r² = 42.25 ( take the square root of both sides )
r = 
= 6.5
When y is directly proportional to x,
y=kx (k is a constant)
when x=12, y=16
12k=16
k=4/3
hence, y=4/3x
The answer is C 5/11
