How to fill out area of circles grade

How to fill out area of circles grade:

1. First, understand the formula for finding the area of a circle, which is A = πr², where A represents the area and r represents the radius of the circle.
2. Measure the radius of the given circle. This can be done by using a ruler or measuring tape. Make sure to measure the distance from the center of the circle to any point on its circumference.
3. Once you have the radius measurement, plug it into the formula A = πr² to calculate the area. Remember to use the value of π as an approximation, typically 3.14 or 22/7, depending on the level of precision required.
4. Calculate the area by squaring the radius and multiplying it by π. For example, if the radius is 5 units, the calculation would be A = π(5)² = 3.14 * 25 = 78.5 square units.
5. Finally, write down the calculated area as the answer to the question or fill it out on the designated space in your grade sheet.
