Answer:
Center = (0,0)
Step-by-step explanation:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] ..... (1)
where, (h,k) is the center of the circle and r is radius.
The given equation is
[tex]3x^2+3y^2=75[/tex]
Divide both sides by 3.
[tex]x^2+y^2=25[/tex]
[tex]x^2+y^2=5^2[/tex] ..... (2)
On comparing (1) and (2) we get
h=0, k=0, r=5
Therefore, the center of the circle is (0,0) and radius of the circle is 5.
