What is the coordinates of the centre and theradius of the circle with equation:

(x - 4)² + (y - 3)² = 25 ?

• Centre (4,3)

  Radius = 5 units

• Centre (4,3)

  Radius = 25 units

• Centre (-4,-3)

  Radius = 25 units

• Centre (-4,-3)

  Radius = 5 units

• Centre (-4,3)

  Radius = 5 units

What is the equation of the circle, with centre (4,2) and diameter 10 units?

• (x + 4)² + (y + 2)² = 25

• (x + 4)² + (y + 2)² = 100

• (x - 4)² + (y - 2)² = 5

• (x - 4)² + (y - 2)² = 25

• (x - 4)² + (y + 2)² = 10
