Answer:
<h2>The area of the spring decreases by 370.52*10⁴cm²</h2>
Step-by-step explanation:
The formula for calculating the area of the circular hot spring =
or 
Initial area of the spring with diameter of 76metres is as shown

If the diameter of the spring decreases by 4 meters over time, the new diameter after decrease will be 76meters less 4 meters which is 72metres.
New area;

Decrease in area = 1444πm²-1296πm²
Decrease in area = 148πm²
= 370.53m²
since 1m²=10⁴cm²
then 370.53m² = 370.52*10⁴cm²
Answer:
