Write the equation in standard form for the cricle with center (-2,4) and radius 9
Shtirlitz [24]

Answer:

( x +2)² + ( y - 4)² = 81

Step-by-step explanation:

The equation for a circle in standard form is ( x – h)² + ( y - k)² = r², where the center is (h, k) and the radius is r.

Putting the question's given information into the formula gives you

[ x – (-2)]² + ( y - 4)² = (9)²

( x + 2)² + ( y - 4)² = 81
