Final answer:
The area of a circle can be calculated using the formula A = π × r^2. This calculation is useful in real-life applications such as farming, construction, and engineering.
Step-by-step explanation:
The formula to calculate the area of a circle is A = π × r2, where A represents the area and r is the radius of the circle.
In real life, calculating the area of a circle is useful in many applications. For example, if you are a farmer and want to know the area of a circular field, you can use this formula to determine how much seeds or fertilizer you will need. Architects and engineers also use the area of a circle to calculate the space required for certain structures or machines.
Overall, understanding how to calculate the area of a circle helps in solving various real-life problems that involve circular shapes.
