How can you find the radius of a circle with coordinates?
Work out the length of the coordinates and half it.
How do you find the length if you have the coordinates and the midpoint?
To work out the length, you need the coordinates of both endpoints. If you have one endpoint and the midpoint, you can treat this as two endpoints and then double the answer you get to calculating the length. To calculate the length, work out the difference in x axis values and difference in y axis values. You then find the square root of (x2+y2). This is the length between the two coordinates.
What are the sub coordinates of equinoctial system of coordinates?
equinoctial system of coordinates
What is the slop of a line that passes through 2 -5?
Two coordinates are needed to work out the slope of the line.
How do you work out the midpoint of a line on a co-ordinate grid?
The x-coordinate of the midpoint is the average of the x-coordinates of the end-points of the line and the y-coordinate of the midpoint is the average of the y-coordinates of the end-points of the line.
