Find the radius of the circle with center (2,2) that passes through (-9,-4)

√157 units or about 12.53 units

Step-by-step explanation:

Equation of circle: (x-h)²+(y-k)²=r²

Center: (h,k) -> (2,2)

Equation so far: (x-2)²+(y-k)²=r²

Plug in (-9,-4) to find r: (-9-2)²+(-4-2)²=r² -> 121+36=r² -> 157=r² -> √157=r

Therefore, the radius of the circle is √157 units or about 12.53 units

if im not mistaking its

step-by-step explanation:  

it would be 3 ÷by 6 because the number on each side
