Question

Find out what the average annual rainfall in your area is. This figure represents a person who is 178
centimetres high. Mark the spot where the rainwater would reach if it could be collected over the
year​

Answer 1

Divide by two to find the average radius. Find the average volume of rain = Depth x radius x radius x 3.14. Find the area at the top of the bucket (this is the area over which the rain is collected). Divide the rainfall volume by this area to get the rainfall.

Good question! Average annual rainfall for a place is generally calculated by averaging the last 30-35 years of annual rainfall. Annual rainfall is the sum of daily rainfall, that can be calculated from raingauge records
