How do you find the are of a circle with only the circumference?
It's important to know the formulas for all these characteristics of circles, and to recognize what they have in common. Area of a circle = πr2 Circumference of a circle = 2πr or dπ Where in the above equations r represents radius, and d is diameter (2r). Both these equations have r in them. Find the radius using the circumference equation, and then plug it into the equation for Area
Why do the standard equations for circles and ellipses have fewer terms when they are centered at the origin of the xy-plane?
If that bothers you, then it's easy to arrange it so that they don't.The standard equation for the circle centered at (A, B) is(x - A)2 + (y - B)2 = R2OK. So if the circle is centered at the origin, then 'A' and 'B' are zero.(x - 0)2 + (y - 0)2 = R2That has just as many terms as any other circle, but most peoplesimply don't bother writing all the zeros for this one. That's allthere is to the mystery.
What is the length of the circle radius when the equation is X's plus Y's 100?
The equation you provided, (x^2 + y^2 = 100), represents a circle centered at the origin (0,0) with a radius of (r = \sqrt{100} = 10). Therefore, the length of the radius of the circle is 10 units.
The circle is centered at the origin and the length of its radius is 8 What is the circle's equation?
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
What number In the standard equation for a circle centered at the orgin should you increase to make the circle larger?
In the standard equation of a circle centered at the origin, which is (x^2 + y^2 = r^2), you should increase the value of (r^2) to make the circle larger. Since (r) represents the radius, increasing (r^2) will result in a larger radius, thus expanding the size of the circle. For example, changing (r^2) from 1 to 4 will increase the radius from 1 to 2, making the circle larger.
The circumference of a circle represents?
The circumference of a circle represents its perimeter and the distance around it.
