If (9, 1) and (1,9) are the endpoints of a diameter of a circle, what is the equation of the circle?

(x - 5)² + (y - 5)² = 32

Step-by-step explanation:

Centre = midpoint of the diameter

(h,k) = (9+1)/2, (9+1)/2 = (5,5)

Radius² = [(9-5)² + ((1-5)²]

= 16 + 16 = 32

Equation:

(x - 5)² + (y - 5)² = 32

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
