Which of the following is the equation of a circle whose center is at the origin and whose radius is 4?
Accepted Solution
A:
Answer:x²+y²=16Step-by-step explanation:the general equation for a circle is given as :(x−h)²+(y−k)²=r²where (h, k) is the coordinate of the center of the circle and r is the radiusin this case h=0, k=0 and r = 4equation becomesx²+y²=4²or x²+y²=16
