- A cylindrical tank with a radius of 3 meters and height of 10 meters is filled with water. If a solid metal sphere with a radius of 2 meters is submerged, how much water (in cubic meters) will overflow?
- Volume of the cylinder: \( V = \pi r^2 h = \pi \times 3^2 \times 10 = 90\pi \) cubic meters.
- Volume of the sphere: \( V = \frac{4}{3} \pi r^3 = \frac{4}{3} \pi \times 2^3 = \frac{32}{3}\pi \) cubic meters.
