The area of a circle can be calculated using the formula:
Area = π × r²
Where:
- π (Pi) is a mathematical constant approximately equal to 3.14159.
- r is the radius of the circle.
In your case, the radius (r) is 5. Now, let’s plug that value into the formula:
Area = π × (5)²
Calculating the square of the radius:
(5)² = 25
So, we have:
Area = π × 25
Now, substituting the value of π:
Area ≈ 3.14159 × 25
Calculating that gives:
Area ≈ 78.53975
Therefore, the area of the circle is approximately 78.54 square units.
This information can be helpful in various applications, whether you’re working on a geometry problem, designing a circular garden, or calculating materials for a round table. Understanding how to calculate the area of a circle is a fundamental concept in mathematics that has practical real-world applications!
