Multiple Choice

Write an equation of a circle centered at $\left( - \frac { 2 } { 3 } , \frac { 1 } { 3 } \right)$ with a radius of $3 \sqrt { 5 }$ .

• A) \(\left( x - \frac { 2 } { 3 } \right) ^ { 2 } + \left( y + \frac { 1 } { 3 } \right) ^ { 2 } = 45\)
• B) \(\left( x + \frac { 2 } { 3 } \right) ^ { 2 } + \left( y - \frac { 1 } { 3 } \right) ^ { 2 } = 45\)
• C) \(\left( x + \frac { 2 } { 3 } \right) ^ { 2 } + \left( y - \frac { 1 } { 3 } \right) ^ { 2 } = 3 \sqrt { 5 }\)
• D) \(\left( x - \frac { 1 } { 3 } \right) ^ { 2 } + \left( y + \frac { 2 } { 3 } \right) ^ { 2 } = 3 \sqrt { 5 }\)
