Question

the parametric equation of the circle x²+y²=9​

Answer 1

Answer:

x=3 and y=0

Step-by-step explanation:

x=3

y=o

x2+y2=9

(3)2 +(0)2

9+0=9

Answer 2

The parametric equation of the circle x²+y²=9

is given by

x = 3 cosФ

y = 3 sinФ

Step-by-step explanation:

The equation of circle is given as x²+y²=9​.

Comparing this equation with the general equation x²+y²= r², we get

r² = 9

r = 3

Hence, the radius of the given circle is 3 units.

Now, the parametric equation of circle x²+y²= r² is given by

x = r cosФ

y = r sinФ

Substituting the value of r, the parametric equation of the circle x²+y²=9 is given by

x = 3 cosФ

y = 3 sinФ
