Notice what you already know about the circle. If you are expected tofind the radius, you will already know the diameter, area or circumference. Choose the equation from step 1 that relates radius to the quantity you already know. Step 3 Divide the diameter by 2 to get r if you know t...
The midpoint of a line is the halfway mark of that line. A radius measures the distance from a circle's middle point, or origin, to its surrounding perimeter, also known as its circumference. The midpoint has much in common with the radius, for the midpoint on a diameter measures its...
Using the Radius to Find the Other Measurements Finding the Radius from Other Measurements Lesson Summary FAQs Activities Where is the radius of a circle? The radius of a circle is the line segment from the center of a circle to a point on the boundary of a circle. Is a radius half ...
The radius of a sphere or a circle is the distance from its center to its circumference. For any regular polygon, the radius is the same from the center to all its vertices. A circle is a regular polygon where the distance from the center to any of its edges is the same. The radius...
How can I find the radius of a circle by knowing two points and its arc length? Do I have to use a numerical method to solve for a trigonometric equation or is there any algebraic or geometric method? Physics news on Phys.org Observing gain-induced group delay betw...
Can you find the center and radius of a circle if the equation is not in standard form? Yes, you can still find the center and radius of a circle if the equation is not in standard form. First, you will need to rearrange the equation into the standard form. Then,...

How to Find a Point on the Unit Circle Given One Coordinate: Vocabulary Unit circle: The circle of radius 1 centered at(0,0). The unit circle is given by the equationx2+y2=1. That is, a point(x,y)is on the unit circle if and only if it satisfies the equation. ...
How to find the radius of a circle with a length on a right triangle? Circumcenter The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of the triangle intersect. It is also the center of the circumcircle of the triangle, which is the c...
