如何在javascript中输入测量圆的表面？

function calculateCircleArea(radius) {
    const pi = Math.PI; // JavaScript中Math对象提供了π的值
    const area = pi * radius * radius; // 计算面积
    return area;
}

// 使用示例
const radius = 5; // 假设圆的半径是5
const area = calculateCircleArea(radius);
console.log(`半径为 ${radius} 的圆的面积是 ${area}`);

function calculateCylinderSurfaceArea(radius, height) {
    const pi = Math.PI;
    const baseArea = pi * radius * radius; // 底面积
    const lateralSurfaceArea = 2 * pi * radius * height; // 侧面积
    const surfaceArea = 2 * baseArea + lateralSurfaceArea; // 总表面积
    return surfaceArea;
}

// 使用示例
const cylinderRadius = 5;
const cylinderHeight = 10;
const surfaceArea = calculateCylinderSurfaceArea(cylinderRadius, cylinderHeight);
console.log(`半径为 ${cylinderRadius}，高为 ${cylinderHeight} 的圆柱的表面积是 ${surfaceArea}`);
