In terms of diameter: Circumference = π·d = 3.14·54 = 169.56(*) In terms of area: Circumference C = √4·π·A = √4·π·2290 = 169.63(*) (*) 169.6 mm exactly or limited to de precision of this calculator (13 decimal places). Note: for simplicity, the operation...
A = area of the circle C = circumference or perimeter r = radius, d = diameter Step-by-step Solution: Circumference of a cicle in terms of radius: Circumference = 2·π·r = 2·3.14·44.5 = 279.6(*) In terms of diameter: Circumference = π·d = 3.14·89 = 279.46(*...
Dimensions define the proportions and can apply to lines, surfaces, and volumes, making the concept universally applicable. 11 The concept of diameter is integral to calculating the circumference and area of a circle, relying on the formulae involving pi (π). This specific measure helps in ...
百度试题 结果1 题目The ratio of the circumference to the diameter of a circle is always a constant. What is this constant? A. π B. 2π C. 3π 相关知识点: 试题来源: 解析 A。圆的周长与直径的比值是π。反馈 收藏
A circle has a diameter of 10 cm. What is the circumference of the circle? (Use π≈3.14) A. 15.7 cm B. 31.4 cm C. 62.8 cm D. 78.5 cm 相关知识点: 试题来源: 解析 B。圆的周长等于π乘以直径,直径是10厘米,π取3.14,那么周长就是3.14乘以10等于31.4厘米。
Circumference = π·d = 3.14·34 =106.76(*) In terms ofarea: Circumference C = √4·π·A= √4·π·907.9=106.81(*) (*)106.8mmexactly or limited to de precision of this calculator (13 decimal places). Note: for simplicity, the operations above were rounded to 2 decimal...
