Answer:
x = 4cos(t) – 1 and y = 4sin(t) + 3
Step-by-step explanation:
Equation of a circle:
The equation of a circle has the following format:

In which:
The centre is is
and r is the radius. The parametric equations are given by:


In this question:

This means that the centre is
and the radius is 4. So, the answer is:
x = 4cos(t) – 1 and y = 4sin(t) + 3
