Calculation example for a spherical corner

Given
Radius r = 12 cm Spherical corner

Find: All parameters of the spherical corner

1. Arc length calculation

For r = 12 cm:

\[P = \frac{r \cdot \pi}{2} = \frac{12 \cdot \pi}{2}\] \[P = 6\pi ≈ 18.85 \text{ cm}\]

The arc length is approximately 18.85 cm

2. Surface area calculation

With r = 12 cm:

\[S = \frac{5 \cdot \pi \cdot r^2}{4} = \frac{5 \cdot \pi \cdot 144}{4}\] \[S = \frac{720\pi}{4} = 180\pi\] \[S ≈ 565.49 \text{ cm}^2\]

The surface area is approximately 565.49 cm²

3. Volume calculation

With r = 12 cm:

\[V = \frac{\pi \cdot r^3}{6} = \frac{\pi \cdot 1728}{6}\] \[V = \frac{1728\pi}{6} = 288\pi\] \[V ≈ 904.78 \text{ cm}^3\]

The volume is approximately 904.78 cm³

4. Summary
r = 12.0 cm P ≈ 18.85 cm
S ≈ 565.49 cm² V ≈ 904.78 cm³
