Half of the diameter D. Double of the diameter 相关知识点: 试题来源: 解析 C。在计算圆的面积公式中,“radius”指“半径”,即直径的一半,选项 A“Diameter”指“直径”,选项 B“Circumference”指“周长”,选项 D“Double of the diameter”指“直径的两倍”,均不符合“radius”的意思。反馈 收藏 ...
Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).The circumference of a circle is found using this formula:ExampleFind the circumference of the circle:Video lessonFind the radius of the circle...
More Examples of Calculating Area Area of a Square The length and width of a square are the same so we just need to multiply the length by the length. Area of a Circle The area of a circle = πr2 where r is the radius of the circle and π is the ratio of a circle’s circumfer...
Calculating the area of a circle is different. It is: Πr² You multiply the pi with the square of the radius. The components of the circle are: Radius: It is the distance from the outside edge of the circle to the center point of the circle. It is the primary component of a ci...

The arc length of a circle is calculated by multiplying the measure of the central angle (in radians) by the radius of the circle. This can be represented by the formula arc length = θ * r, where θ is the central angle and r is the radius of the circle. What is the un...

Figure 5: The radius, diameter, and circumference of a circle. (click to enlarge) We know we have 54” curves on this circle. With O Gauge track, the 54” measures the diameter of the circle those tracks would make (in other scales, size of the curve indicates the radius of the ...
