The answer depends on what information is available and in what form.
The simplest solution is to write the equation of the circle in the following form:
(x - a)^2 + (y - b)^2 = r^2
Hiving done that, the coordinates of the centre are (a, b), and the circle's radius is r.
A diameter of a circle is twice the length of a radius. Think of a diameter as two radii, both originating at the center of the circle and extending out at 180 degrees to each other to reach the edge of the circle. In this example, if the radius is 1.5, the diameter would be 3.
The radius of a circle is a straight line from the centre of the circle to its circumference.
Yes, providing that each radius is in the same circle
Draw two diameters perpendicular to each other. Draw a smaller circle with the same centre such that the radius of the inner circle is 'r' and the radius of the outer circle is 'r√2.' [Or, the radius of the outer circle is R and the radius of the inner circle is R/√2.]
Oh, dude, you're hitting me with some geometry now! So, the radius of a circle is half of its diameter, right? That means if the diameter is 50mm, the radius would be 25mm. And if you want to find the diameter from the radius, just double it! Simple math, man.
The distance to the center.
The distance to the center.
The distance to the center.
The Radius
there is a center point, an arc, a radius, a diameter, a chord.
A circle has a radius because each radius is the same. A square does not because if it did, not every radius would be the same. Since a square is a regular polygon, it has an apothem, which goes from the center to the middle of a side, so it doesn't need a radius.
The radius of the circle is 7.
In science, the radius of a circle typically represents the distance from the center of the circle to any point on its circumference. This can be used to calculate various properties such as area, circumference, and relationships between different geometric shapes.
A diameter of a circle is twice the length of a radius. Think of a diameter as two radii, both originating at the center of the circle and extending out at 180 degrees to each other to reach the edge of the circle. In this example, if the radius is 1.5, the diameter would be 3.
Perpindicular lines are like the lines in the letter "T". The intersect each other at a 90 degree angle. A radius is the distance from the center of the circle to the circle itself. It is half the circle's diameter.
To find the radius of the circle, we can use the Pythagorean theorem. The chord divides the circle into two equal parts, each forming a right triangle with the radius. The radius, the distance from the center to the chord, and half the length of the chord form a right triangle. Using the Pythagorean theorem, we have (radius)^2 = (distance from center)^2 + (1/2 * chord length)^2. Substituting in the given values, we get (radius)^2 = 8^2 - (1/2 * 4.2)^2. Solving for the radius gives us a radius of approximately 7.48 cm.
Why is this an automotive question? The radius of any circle is half of the diameter.
