The circle is centered at the origin and the length of its radius is 8 What is the circle's equation?
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
What is the center and radius of the circle with equation (x 9)2 (y 5)2 64?
If you mean: (x+9)^2 + (y+5)^2 = 64 Then the center of the circle is at (-9,-5) and the radius is 8
What is the circumference of a circle if the area is 64 pi?
Area = pi*r2 = 64*pi so that r2 = 64 or r = 8 Then circumference = 2*pi*r = 16*pi
What is the answer for the circle of 128 ft what is the radius of the circle?
If the circumference is 128 feet, the radius is 20.37 feet. If the diameter is 128 feet, the radius is 64 feet.
X2 plus y2 equals 64. what is the radius?
That's the equation of a circle with its center at the origin and a radius of 8.
