A circle can be drawn with any center and any radius.
A circle in black color with center A. Point B is present on the circumference of this circle. We can move the points A and B. Change the positions of A and B of and observe how the position and size of the circle changes. Equation of the circle ‘c’ is mentioned in black color.  Coordinates of point A and radius are mentioned in the circle.

FAQs on A circle can be drawn with any center and any radius. - Class 9

1. Can a circle be drawn with any center?
Ans. Yes, a circle can be drawn with any center. The center of a circle is a point inside the circle from which all points on the circle are equidistant. So, by choosing any point as the center, a circle can be drawn.
2. Is it possible to draw a circle with any radius?
Ans. Yes, a circle can be drawn with any radius. The radius of a circle is the distance from the center to any point on the circle. By choosing a specific distance as the radius, a circle can be drawn accordingly.
3. Do all circles have the same size?
Ans. No, circles can have different sizes. The size of a circle is determined by its radius. Circles with larger radii have larger sizes, while circles with smaller radii have smaller sizes. Therefore, circles can have varying sizes depending on their radii.
4. Are there any limitations in drawing circles?
Ans. Yes, there are certain limitations in drawing circles. One limitation is that a circle cannot be drawn if the radius is zero, as it would be just a single point. Additionally, if the given center is outside the drawing area or if the radius is too large to fit within the available space, it may not be possible to draw a circle accurately.
5. Can circles be used in real-life applications?
Ans. Yes, circles have various real-life applications. They are commonly used in fields such as architecture, engineering, and design. Circles are used to create wheels, gears, and pulleys, among other things. They are also essential in mathematical and scientific calculations, such as calculating areas, angles, and distances.
