Geometry has many real applications. My dad had a problem of calculating how the volume of a big water tank in terms of water buckets. I did try giving measurements in liters but they did not make sense as he wanted a measure he could relate to. So I had to solve the challenge though it was not easy. First I measured the diameter of the big tank and the diameter of the water bucket. Assuming that both containers were perfect cylinders I was able to calculate the volume of the big tank by simply dividing the squares of the radius multiplied by the heights of the containers. In my calculation I figured out that since finding the volume of either of the container involved the constant Pie, eventually the constants cancelled out. I found that the big tank was equal to 1000 buckets, and my dad as happy about it.
