Answer:
The equation of circle is x² + y²– 16x = 0

Step-by-step explanation:

Given: Centre of circle: (0,8) and Radius = 8.

Formula: Equation of circle if centre (h,k) and radius r

(x – h)² + (y – k)² = r²

Where, (h,k)-> (0,8) and r=8

Now, we will put the value of centre and radius into formula

Equation of circle:

(x – 0)² + (y – 8)² = 8 ²

x² + (y – 8)² = 64

In expanded form equation of circle.

x² + y² – 16x + 64 = 64

x²+ y²– 16x = 0

Hence, The equation of circle is

x² + y² –16x = 0
