A straight line from the center of a circle to the edge is called the radius. A straight line that passes from one side of a circle to the other through the center is called the diameter. The distance around the outside of a circle is called the circumference. All points on the edge ...
A. 9 B. 18 C. 36 D. 9π E. 18π 相关知识点: 试题来源: 解析 B The formula for the area of a circle is πr2. Therefore, the radius of this circle is the square root of 81, or 9. The diameter is twice the radius, so 18.反馈...
