Answer:

see explanation

Step-by-step explanation:

the equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

(1)

x² + y² = 196 ← is in this form

with centre = (0, 0 ) and r = [tex]\sqrt{196}[/tex] = 14

(2)

x² + y² = 100 ← is in this form

with centre = (0, 0 ) and r = [tex]\sqrt{100}[/tex] = 10
