Questions & Step-by-Step Solutions

What is the area of a circle with a radius of 10 m? (2023)
  • Step 1: Identify the formula for the area of a circle, which is Area = πr².
  • Step 2: Substitute the radius (r) into the formula. Here, the radius is 10 m.
  • Step 3: Calculate the square of the radius: 10² = 100.
  • Step 4: Multiply the result by π (approximately 3.14): Area = π * 100.
  • Step 5: Calculate the area: Area ≈ 3.14 * 100 = 314 m².
  • Area of a Circle – The area of a circle is calculated using the formula A = πr², where r is the radius.
