Today you will need to look at the following problem and explain what Susan did incorrectly.

see explanation

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 3)² + (y + 4)² = 36 ← is in standard form

with (h, k) = (3, - 4 ) = centre and r = = 6

Susan interpreted the values of h and k incorrectly by using the values - 3 and 4 instead of taking the negative of them.

She also divided 36 by 2 , thus omitting the root of 36
