A line of any length may act as the radius of a circle. The radius is the distance from the centre to the perimeter of a circle.
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
When you draw a circle in math, and you draw a triangle inside of it, 2 of the lines should be the radius of the circle, and the third (bottom) line that is not the radius is the chord.
The radius is the distance from the center of the circle to its edge. No matter how you draw this radius, it is one value of one length only, for any given circle.
To draw a circle inside another circle in MSWLogo, you can use the REPEAT command along with the CIRCLE command. First, use the CIRCLE command to draw the outer circle, then adjust the pen position to the center and use the CIRCLE command again with a smaller radius for the inner circle. Here's a simple example: CIRCLE 100 ; Draw outer circle with radius 100 PENUP SETXY 0 -50 ; Move to inner circle position (50 units up) PENDOWN CIRCLE 50 ; Draw inner circle with radius 50 This will create a smaller circle inside the larger one.
Radii are always positive. No, it is not possible to draw a circle with negative radius.
A line of any length may act as the radius of a circle. The radius is the distance from the centre to the perimeter of a circle.
In QBasic, you can draw a circle using the CIRCLE statement. The syntax is CIRCLE (x, y), radius, where (x, y) is the center of the circle, and radius is the radius of the circle. For example, CIRCLE (100, 100), 50 would draw a circle with a center at coordinates (100, 100) and a radius of 50 pixels. You can also specify a color by adding a third parameter, like CIRCLE (100, 100), 50, 15 for a circle in color 15.
Draw two diameters perpendicular to each other. Draw a smaller circle with the same centre such that the radius of the inner circle is 'r' and the radius of the outer circle is 'r√2.' [Or, the radius of the outer circle is R and the radius of the inner circle is R/√2.]
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.

When you draw a circle in math, and you draw a triangle inside of it, 2 of the lines should be the radius of the circle, and the third (bottom) line that is not the radius is the chord.
The radius is the distance from the center of the circle to its edge. No matter how you draw this radius, it is one value of one length only, for any given circle.
The area of a circle is: pi times radius squared
To draw an arc in QBasic, you can use the Circle statement, specifying the center coordinates, radius, and the starting and ending angles. The syntax is Circle (x, y), radius, start_angle, end_angle. For example, Circle (100, 100), 50, 0, 90 would draw a quarter-circle arc from 0 to 90 degrees centered at (100, 100) with a radius of 50.
The default method for drawing a circle is to specify a center point and radius.You can draw circles using any of the following methods:Center-RadiusCenter-DiameterTwo pointsThree pointsRadius-Tangent-TangentConvert Arc to CircleTo draw a circle by specifying its center and radiusDo one of the following:Choose Draw> Circle>center, radiusOn the Draw 2D toolbar, click the Circle Center-Radius tool.Type circle and then press Enter.Specify the center point.Specify the radius of the circle.
