According to the distance formula, this is √(x−0)2+(y−0)2=√x2+y2. A point (x,y) is at a distance r from the origin if and only if √x2+y2=r, or, if we square both sides: x2+y2=r2. This is the equation of the circle of radius r centered at the origin.

The diameter of a circle multiplied by pi gives you the circumference, or the distance around the circle. Draw two lines from the radius of your circle, each connecting to one of the two points you're using to measure arc distance.

No. The diameter of a circle is the longest distance away from each other 2 points on a circle can be. ... (Note: When the radius is 2, the diameter will be equal to the radius squared, because the radius squared will be equivalent to the radius times 2, which is the diameter.

It is calculated by multiplying the distance across the center (diameter) by Pi (3.1416). If I know the radius of a circle, how I can find the circumference? Double the radius to get the diameter. Then multiply by pi to get the circumference.

Objects moving in circles have a speed which is equal to the distance traveled per time of travel. The distance around a circle is equivalent to a circumference and calculated as 2•pi•R where R is the radius. The time for one revolution around the circle is referred to as the period and denoted by the symbol T.

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.

Use the formula D2 = X2 + Y2 to find the squared distance between two points. For example, if X = 4 and Y = 5, then D2 = 42 + 52 = 41. Thus, the square of the distance between the coordinates is 41. Take the square root of D2 to find D, the actual distance between the two points.

Distance Formula and Pythagorean Theorem The distance formula is derived from the Pythagorean theorem. To find the distance between two points (x1,y1) and (x2,y2), all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below.

Using the Radius. Write down the formula for finding the circumference of a circle using the radius. The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr.

The distance from the center to a point on the circle is called a radius. Every circle has an infinite number of possible diameters. The formula for finding the diameter of a circle is two times the radius (2 * radius).

First, double the radius to get the diameter (radius x 2, or radius + radius). One you have the diameter, you can use the equation C = πd.

Multiply the distances together and then multiply the result by 2 times the cosine of the angle between the stars. Subtract the result of step 2 from the result of step 1. Take the square root of the result of step 3. This is the distance between the two stars.

Take the coordinates of two points you want to find the distance between. Call one point Point 1 (x1,y1) and make the other Point 2 (x2,y2). It does not terribly matter which point is which, as long as you keep the labels (1 and 2) consistent throughout the problem.

The distance between the centers of two holes can be checked with a vernier caliper. The position of the caliper in measuring the inside distance between two holes is shown in Figure 29-10. To determine the setting on the caliper, subtract the radius of each hole (one-half the diameter) from the center distance.
