Q 5: Find radius & centre of the circle x2+y2=16
​

Answer 1

Answer:

4 is the radius and centre is (0,0)

Step-by-step explanation:

general equation of a circle is

(x-h)^2 +(y-k)^2 = r^2

where (h,k) is the centre of the circle and r is the radius of the circle

so comparing the equation wid the general equation

we get the centre as 0,0

and radius as 4
