radius = 11 cm
The surface area of a cylinder if the radius is 3 and the height is 11 equals 263.9 square units.
This is an equation that describes an ellipse. Its center would be located at the point (0, 0), its x radius would be 8, and its y radius would be 11.
Centre = (0,0), the origin; radius = 11
5.5 is the radius.
The distance from Earth to Sun is about 150 million kilometers. It isn't clear what you mean with "in diameters".
radius = 11/2 = 5.5 cm
If this is the equation of a circle, the answer is 11, except that there needs to be a plus sigb between the x2 and the y2
Its usually defined by the diameter of the ball, like an 11 inch disco ball would have a diameter of 11 inches, not a radius of 11 inches.
the radius is half the diameter. radius is half of 11. Which is 5.5.
The radius is 11.
Area of the circle: pi*11^2 = 121*pi square units
