18 views

To calculate the area of a circle, use the formula A = πr², where A is the area and r is the radius. Simply square the radius (multiply it by itself) and then multiply by π (approximately 3.14159) to find your answer. For example, if the radius is 5 units, the area would be π × 5² = 78.54 square units.

FAQs & Answers

  1. What is the formula for the area of a circle? The formula for the area of a circle is A = πr², where 'A' stands for area and 'r' is the radius.
  2. How do you find the radius from the area? To find the radius from the area, rearrange the formula to r = √(A/π).
  3. What if the radius is in different units? Make sure to convert the radius to the same units before calculating the area for accurate results.
