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

Give me 2 examples of problems that can be solve through cartesian coordinate system?
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.
What is the circumference and area of a circle in cm whose centre is at the origin passing through the coordinates of 5 12 and 12 5 on the Cartesian plane?
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
What do graph you get if you make both the angle and the distance parameters in an equation?
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.
Prove that the equation of a straight line is given by y equals mx plus c .?
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.
What is the centre and area in cm of a circle whose circumference cuts through the points of 1 0 and 7 -6 and 7 0 on the Cartesian plane?
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.

What is the center and radius of a circle whose circumference passes through the points 5 0 and 3 4 and -5 0 on the Cartesian plane?
It has centre (0, 0) and radius 5.

What is the equation of the line that has a slope of 4 and passes through the point 310?
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.
Why does a circle have infinite lines of symmetry?
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).

What does rotate mean in maths?
A rotation turns a shape through an angle around a fixed point usually on the Cartesian plane
In math how do rotations affect coordinates?
A rotation turns a shape through an angle at a fixed point thus changing its coordinates
What is the centre and radius of a circle enscribed through the points of 6 2 and 8 -2 and 0 2 on the Cartesian plane?
It works out that the circle's centre is at (3, -2) and its radius is 5 on the Cartesian plane.
