How do you know that the diameter in a circle is the longest possible chord in the circle?
Because it is a line through the center of the circle and it is impossible for a line that is not through the center to be longer than one that is through the center.
What is the interior of a circle?
The set points whose distance from the center of the circle that is less than the radius. A disk.
What is a cord that is drawn from the center of a circle?
A cord that crosses the center of a circle is a diameter, which divides the circle into two equal halves. It is a line segment, and it is the longest cord that can be drawn within a circle.However, if the segment begins at the center rather than crosses through it, and has the other endpoint on the circumference of the circle, it is not a cord, but is a radius of that circle.
Is a circle less than or equal to the radius?
The radius of a circle is the distance from the center of the circle, out to the edge of the circle. The distance all the way across the circle is the "diameter." Half of the diameter is the radius.
What is the line that joins two points on the circle?
That's a 'chord' of the circle.If it passes through the center of the circle, then it's also called a 'diameter'of the circle, and no other chord of that circle can be longer than it is.
How do you find out if each point is on inside or outside of the circle?
Find the distance of the point from the centre of the circle. If the distance is - less than that radius then the point is inside the circle, - equal to the radius then the point is on the circle, and - greater than that radius then the point is outside the circle.

How to draw great circles and small circles drawn?
To draw a great circle on a sphere, start by defining the diameter as the largest circle that can be drawn on the sphere's surface. For small circles, choose a point on the sphere and draw a circle with that point as the center and the radius less than the sphere's radius. Remember that the center of a small circle lies outside the circle on a sphere's surface.
The area of the circle increases the area of the rectangle?

What is the difference between diameter and circumference?
Diameter is the distance across a circle through the center. Circumference is the distance around the outside of a circle. Circumference is always pi (3.14) times larger than diameter.Note:pi is approximately 3.14
Chemical reactions in cells are faster than the same reactions outside cells?
Chemical reactions in cells are faster than the same reactions outside cells.
Sketch a circle with two moncongruent chords Is the longer chord father from the center or closer to the center than the shorter chord?
The longer chord is closer to the center of the circle. Chords are only equidistant from the center of a circle if they are congruent. I hope that helps.
Definition of an interior of a circle?
the set of points whose distance from the center of the circle is less than that of the radius.

Can there be more than 4 radius in a circle?
Yes, providing that they stem from the center of the circle to its circumference.
Is the inside of a spiral parking ramp steeper than the outside?
Yes. Consider two circles, one inside the other with the same center point. Both circles change in elevation equally, however, the inner circle has a smaller circumference than the outer circle. Thus the inner circle has a shorter distance to travel the same amount of rise as the outer circle, resulting in a steeper slope.
