Answer:

and t ∈ [0,2π]
Step-by-step explanation:
The standard equation for circle is:

Comparing our equation with standard

h= 0,
k= 3
r= 4 (as in standard r², so r =√ r²)
Required:
Parametric equations of the circle
Formula:

Putting values of r and h and k we get

As we need to start the object at (4,3)
x(0) = 4 and y(0) = 3
and the period is 2π
As the rotation is starting clock wise we will invert the value of t i.e -t

and t ∈ [0,2π]
You just need to know how much 10% is and then you just divided what 10% is and that will be equal to 5% and then you just add the 10 % and 5%
