给定圆锥的斜高、高度和半径，我们必须计算圆锥的体积和表面积。

• 圆锥：圆锥是一种三维几何形状。它由一个圆形的底部和一个弯曲的侧面(侧面)组成，末端是一个称为顶点或顶点的尖端。

• 圆锥体积：圆锥的体积由公式给出 -

volume = 1/3(pi * r * r * h)

• 其中 r 是圆形底的半径，h 是高度(从底到顶点的垂直距离)。

• 圆锥的表面积：圆锥的表面积由公式给出 -

area = pi * r * s + pi * r^2  

• 其中 r 是圆底的半径，s 是圆锥的斜高。

例子：

Input :

radius = 5

slant_height = 13

height = 12

Output :

Volume Of Cone = 314.159

Surface Area Of Cone = 282.743

Input :

radius = 6

slant_height = 10

height = 8

Output :

Volume Of Cone = 301.593

Surface Area Of Cone = 301.593

{

    return (float(1) / float(3)) * pi * 

                             r * r * h;

}

  // Function to calculate

// Surface area of cone

float surface_area(float r, float s)

{

    return pi * r * s + pi * r * r;

}

  // Driver Code

int main()

{

    float radius = 5;

    float slant_height = 13;

      // Printing value of volume 

    // and surface area

    cout << "Volume Of Cone : "

        << volume(radius, height) << endl;

    cout << "Surface Area Of Cone : "

        << surface_area(radius, slant_height);

    return 0;

}
