Based on the calculations, the approximate area covered by the reservoir is equal to 0.28 km².
<h3>What is the area of a circle?</h3>
The area of a circle simply refers to the space occupied or the region enclosed by a circle within its boundary, and in a two-dimensional plane.
<h3>How to calculate the area of a circle?</h3>
Mathematically, the area of a circle is calculated by using this formula:
Area = πr²
<u>Where:</u>
r is the radius of a circle.
<u>Given the following data:</u>
Diameter of circle = 0.6 kilometer.
π = 3.14.
Radius = 0.6/2 = 0.3 km.
Substituting the given parameters into the formula, we have;
Area = π × 0.3²
Area = 3.14 × 0.09
Area = 0.28 km².

The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometers (1,400 mi) over an area of approximately 344,400 square kilometers (133,000 sq mi).

What are coral reefs?</h3>
Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny living animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups.
<h3>
Coral Reefs of India:</h3>
India has four coral reef areas: the Gulf of Mannar, Andaman and Nicobar Islands, Lakshadweep Islands, and the Gulf of Kutch. Coral reefs protect humanity from natural calamities. They provide revenue and employment through tourism and recreation.
<h3>
Coral Reefs of Australia:</h3>
The reef is located in the Coral Sea, off the coast of Queensland, Australia, and is separated from the shore by a strait that is up to 100 miles wide and 200 feet deep in places. The Great Barrier Reef is the world's largest single structure built by living beings, visible from space.
