Answer:
Radius = 14 units
Center = ( 6, 8)
Step-by-step explanation:
The correct equation is ,
=> (x-6)² + (y-8)² = 196
=> (x-6)² + (y-8)² = 14²
- Compare to Standard form , which is ,
=> ( x - h)² + ( y - k)² = r²
- ( h , k ) is Center
- r is radius
Hence on comparing we have,
- Radius = 14 units
- Center = ( 6, 8)
