<h3>Answer:</h3>
centre = (0,5/2)
radius = 3/2
<h3>Step-by-step explanation:</h3>
The centre-radius form of the circle equation is in the format
(x – h)² + (y – k)² = r²,
with the centre being at the point (h, k) and the radius being "r"
Given in the question an expression which can be write as
<h3> (x – 0)² + (y – (5/2))² = (3/2)²</h3>
So, by translating we can say that
centre = (0,5/2)
and
radius = 3/2
