Circles have properties that are common to all of them. One such property is the relationship between a circle's diameter and its radius. You can use this property, when it's expressed as an equation, to solve for the radius of any circle, as long as you know that circle's diameter. ...

试题来源: 解析 C A diameter equals twice a radius, so the diameter is 2×8=16. 如果 一个圆的半径是8cm,则它的直径是( ). A.4cm B.8cm C.16cm D.64cm 直径是半径的两倍,所以周长是2×8=16. 答案为C=16cm. 故选C.反馈 收藏
The diameter of a circle is the distance across a circle directly through its center. The radius is one half of the diameter in measurement. The radius measures the distance from the very center of the circle to any point on the circle. You can calculate either of the measurements if you ...
Now that we can easily calculate the circumference from either diameter or radius, we can use this formula to find the perimeter of a semi circle or arc length. Arc length can be explained as simply the length of a section of the boundary around a circle. When trying to find the circumfe...
figure. It is the enclosing boundary, or the edge. Theradiusof a circle is a straight line segment from the circle's center point to the outer edge. This can be measured using the center point of the circle and any point on the edge of circle as its end points. Thediameterof a ...
Next, there are two simple ways to calculate the diameter of a hexagon. Measure the side length and multiply it by 2. Multiply the radius by 2. (The distance from the intersection of the two sides to the center is called the radius.) ...
Let's say I want to create a circle with a radius of 30 mm. Ok... so I... 1. Create a straight path (using the pen tool?) of 30 mm starting at 0,0 (from 0,0 to 0,30). 2. Select the 0,0 (with the direct selection tool?) extreme of the straight path (only on...
For cyclecomputers that require a diameter value, divide the result by 3.1416 (π), and for those which require a radius value, divide the result by 6.2832 (2 x π). Once you have measured the rolling circumference, use the formula indicated to find the calibration number for the cycle...
for example its diameter, its circumference, its area and even its volume (if you're dealing with a three-dimensional circle, also known as a sphere). If you know any of these other measurements, you can work backwards from standard formulas to figure out the circle or sphere's radius. ...
