Question: A circular swimming pool has a diameter of 10 meters. What is the area of the pool in square meters? (Use π = 3.14)

Options:

Correct Answer: 78.5

Solution:

Radius = diameter / 2 = 10 / 2 = 5 meters. Area = π × radius² = 3.14 × 5² = 3.14 × 25 = 78.5 square meters.

A circular swimming pool has a diameter of 10 meters. What is the area of the pool in square meters? (Use π = 3.14)

Step 1: Identify the diameter of the swimming pool, which is given as 10 meters.
Step 2: Calculate the radius of the pool by dividing the diameter by 2. So, radius = 10 meters / 2 = 5 meters.
Step 3: Use the formula for the area of a circle, which is Area = π × radius².
Step 4: Substitute the value of π (3.14) and the radius (5 meters) into the formula. So, Area = 3.14 × (5 meters)².
Step 5: Calculate the square of the radius. (5 meters)² = 25 square meters.
Step 6: Multiply π (3.14) by the squared radius (25 square meters). So, Area = 3.14 × 25 = 78.5 square meters.

Area of a Circle – Understanding how to calculate the area of a circle using the formula A = π × r², where r is the radius.
Diameter and Radius Relationship – Recognizing that the radius is half of the diameter and correctly applying this relationship in calculations.
