A water tank is placed is placed on a concrete tower which is a regular hexagon of 5 m sides and height of 35 m. Find the volume of the concrete used to make it.

---

Cross-sectional area = 6 x ½ x 5 x 5 sine 60° (area of a triangle = ½ ab sin C)
=64.95 m^2
Volume of the tower= 64.95 x 35
=2273.25 m^3
