Answer 1

Hello....

✔️To find the equation of a circle the formula given is :-
(x – h)2 + (y – k)2 = r2

✔️where the centres are (h,k)...

✔️Now substitute (h, k) i.e(0,2)

✔️Where radius is given as r=2 cm

✔Expand using

⏹( a - b)2 = a2 + b2 - 2ab

and

⏹( a +b)2 = a2 + b2 + 2ab...

✔️ Hence you get a equation as the equation of circle...
