The area of a circle can be calculated using the formula: A = πr², where:
- A is the area of the circle.
- π (pi) is a constant approximately equal to 3.14159.
- r is the radius of the circle.
In this case, the radius (r) of the circle is given as 1. Plugging this value into the formula, we get:
A = π(1)² = π * 1 = π
So, the area of a circle with a radius of 1 is simply π, which is approximately 3.14159.
To summarize, the area is:
A ≈ 3.14
This means that if you have a circle with a radius of 1, its area will be a little over 3.14 square units!
