1) Below Is the Bar Graph That Represents the Data for the Rainfall of the First Five Months of a Place.
Observe the Graph Properly and Answer the Following Question:
a) In Which Month Was the Highest Rainfall Recorded?
b) What Is the Average Rainfall for the First Five Months?
c) If the Total Rainfall Falls on the Area of 16 Square Cm, Then Calculate the Volume of the Rain.
a) According to the graph, the highest bar is in January. Therefore, the highest rainfall is recorded in January and is equal to 111 cm.
b) The graph shows that:
In January, the rainfall depth was 111 cm.
In February, the rainfall depth was 56 cm.
In March, the rainfall depth was 73 cm.
In April, the rainfall depth was 20 cm.
In May, the rainfall depth was 13 cm.
Add all the rainfall depths to get the total rainfall.
Total rainfall = 111 + 56 + 73 + 20 + 13 cm
= 273 cm
The total rainfall = 273 cm
Number of months = 5
Average rainfall of the five months= 273/5=54.6
c) The formula to calculate the volume of rainwater is:
Volume = Area × Total rainfall
= 16 × 273
= 4368
Therefore, 4368 cubic cm of rainwater was collected.
