【答案】 分析： 根据圆角轴截面的定义结合正三角形的性质，可得圆锥底面半径长和高的大小，由此结合圆锥的体积公式，则不难得到本题的答案．

2012年5月24日 一个圆锥的轴截面是一个边长为a的正三角形,求这个圆锥的侧面积与全面积依题意得R=1/2a ， L=a 侧面积=1/2（a^2）π 全面积=1/2（a^2）π
2024年5月7日 圆锥的轴截面(axial section of a circular cone)是一种与圆锥轴有关的截面，用一个过圆锥的轴的平面去截圆锥，所得的截口三角形称为圆锥的轴截面，也称为圆

要求内切球的半径，实际上就是求这个圆的半径，也就是求中心到边的距离。 最简单的方法是连接中心和三个顶点。 三角形的面积被等分为三个全等的小三角形。

解析 本题主要考查圆锥中的几何量的计算。 圆锥的轴截面是边长为 2 的正三角形，则 2R = 2 ， h = 2 × 3√ 2 = 3√ ，得 R = 1 ，由圆锥的体积公式得 V = 1 3 πR2h = 1 3 结果一 题
.jpg)
正三角形边长为a=l=2r∴r＝½a圆锥底面积为πr²＝πa²×¼ 侧面展开图为以l为半径的半圆所以侧面面积为½×πl²＝½πa² πa²×¼＋½πa²＝¾πa²
.jpg)
【解析】 【分析】 由题可知圆锥底面半径为1，母线长为2，即可直接计算侧面积 【详解】 因为圆锥的轴截面是边长为2的等边三角形， 所以该圆锥底面半径为1，母线长为2， 所
.jpg)
一个圆柱和一个圆锥的轴截面分别是边长为a的正方形和三角形,则它们的表面积之比为底面半径是 a / 2 圆柱的表面积是 2π﹙a / 2﹚²＋πa²＝3πa²／2 圆锥的表面积是 π﹙a /
.jpg)
分析 根据轴截面的性质得出圆锥母线长为2，底面半径为1，代入面积公式计算即可． 解答 解：圆锥的母线长l=2，底面半径r=1， ∴圆锥的表面积S=πrl+πr 2 =π×1×2+π×1 2 =3π．
