The standard form is (x - h)^2 + (y - k)^2 = r^2
(h,k) is the center
(x - 0)^2 + (y - 0)^2 = 8^2
x^2 + y^2 = 64
ANS : d.) x^2 + y^2 = 64

positive. Radius is defined as r. the middle of a circle is (h,ok) The equation of a circle is = (x-h)^2 + (y-ok)^2 = r^2 Given the archives contained in the issue.. center is (0,0), r=15 h=0 ok=0 r =15 We plug contained in the archives. on condition that we are "subtracting" 0, we are able to easily write it as x and y. x^2 + y^2 = 15^2 x^2 + y^2 = 225

the equation is :
x^2+y^2=64
you get this by the following method:
(x-0)^2+(y-0)^2=8^2
=> x^2+y^2=64

(x-0)^2+(y-0)^2=8^2
x^2+y^2=64
The answer is [d].
If ur not able to solve that easy question, then i'll advice u to practice and ask some difficult questions here.
