The circumference of a semicircle is 15.42 cm. What is the radius? (Use π≈3.14) A. 3 cm B. 4 cm C. 5 cm D. 6 cm 相关知识点: 试题来源: 解析 A。半圆的周长等于圆周长的一半加上直径,设半径为 r,圆周长的一半是πr,直径是 2r,所以半圆周长是πr + 2r,即(π + 2)r。已知...
看题,A semicircle of radius r is drawn with centre V and diameter UW. The line UW is then extended to the point X, such that UW and WX are of equal length. An arc of the circle with centre X and radius 4r is then drawn so that the line XY is tangent to the semicircle at Z,...
The circumference of a semicircle is 15.42 centimeters. What is its radius? A. 3 centimeters B. 4 centimeters C. 5 centimeters D. 6 centimeters 相关知识点: 试题来源: 解析 A。半圆的周长等于圆周长的一半加上直径,设半径为 r,半圆周长为πr + 2r = 15.42,解方程可得半径为 3 厘米。
