Question

A circle is represented by the equation below: (x + 8)2 + (y − 3)2 = 100 Which statement is true?

Answer 1

Answer:

D) The circle is centred at (-8,3) and has a diameter 20

Step-by-step explanation:

Explanation:-

Given that the circle

        ( x + 8)² +( y-3)² = 100

   ⇒ ( x + 8)² +( y-3)² = 10²

Standard form of the circle ( x-h)² +(y-k)² = r²

Centre of the circle (h , k) = (-8 , 3)

Radius of the circle  r = 10

Diameter of the circle 'd' = 2r = 2(10) =20

Final answer:-

The circle is centred at (-8,3) and has a diameter 20
