which of the following is an equation of the circle in
the xy-plane that has center (0,0) and radius 4?
a) x2 + y2 = 4
b) x2 + y2 = 8
c) x2 + y2 = 16
d) x2 + y2 = 64

C

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ← where r is the radius

here r = 4, thus

x² + y² = 4², that is

x² + y² = 16 → C

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

answer. d.289 hope that
