Activity 1: Find the center and the radius of a circle. Complete the table below. Center Radius Equation 1. x2 + y2 = 16 2. (x-4)2 + (y + 2)2 = 25 3. (x + 5)2 + y + 3)2 = 64 4. x2 + y2 + 10x - 8y + 16 = 0 5. x2 + y2 - 8x + 4y - 5 = 0​

Sagot :

Answer:

The center is (5,-4)

Step-by-step explanation:

and the radius is 3 x^2-10x+y^2+8y+32=0 Completing the squares x^2-10x+25+y^2+8y+16=-32+25+16 (x-5)^2+(y+4)^2=9=3^2
