If a cone is cut by a plane perpendicular to the axis of the cone, then the section is a

Choose an answer

parabola

circle

hyperbola

ellipse

The equation of the circle witch centre (-3, 5) and radius 7 is

Choose an answer

(x-3)²+ (y+5)²= 7²

(x-3)²+ (y-5)²= 7²

(x+3)²+ (y+5)²= 7²

(x+3)²+ (y-5)²= 7²
