Points: (0, 0) and (3, 4)
Using Pythagoras: distance fro (0, 0) to (3, 4) = 5 cm which is the radius
Circumference: 2*pi*5 = 31.416 cm rounded to three decimal places
Area: pi*5^2 = 78.540 square cm rounded to three decimal places
1.Finding the solution to a system of linear equations can be found using cartesian coordinates. 2. Graph a circle and you can find the radius using cartesian coordinates.
Using Pythagoras: distance from (0, 0) to (12, 5) = 13 which is the radius Circumference: 2*pi*13 = 81.691 cm to three decimal places Area: pi*13^2 = 530.929 square cm to three decimal places
You get a graph based on polar coordinates rather than Cartesian coordinates. Some shapes have simpler equations in polar coordinates: for example, a circle with centre at the origin and radius r, is simple R = r. A straight line through the origin and gradient (slope) m is tan(q) = m.
The Cartesian coordinates in the form of the linear equation y = mx+c is a straight line that can be plotted on a graph where m is the slope and c is the intercept through the y axis. For example: y = 3x+2 means that 3 is the slope and that 2 is the intercept and when plotted on a x axis and y axis graph will produce a straight line. The idea of Cartesian coordinates was the brainchild of the French mathematician Rene Descartes in the early 17th century.
It works out that the centre of the circle is at (4, -3) on the Cartesian plane and its area is 56.549 square cm rounded up to three decimal places.

It has centre (0, 0) and radius 5.

It appears that the point has only one coordinate: 310. In two dimensional space, such as the coordinate (or Cartesian) plane, a point needs two coordinates.
Because the distance from one point at the circumference through the center to another point at the circumference is always the same, at an infinite set of coordinates along the circle (anywhere, relative to the size of the circle, and always providing an axis which perfectly dissects the circle).

A rotation turns a shape through an angle around a fixed point usually on the Cartesian plane
A rotation turns a shape through an angle at a fixed point thus changing its coordinates
It works out that the circle's centre is at (3, -2) and its radius is 5 on the Cartesian plane.
