Questions & Step-by-Step Solutions

If a radar system can detect objects up to 100 km away, what is the maximum area it can cover? (2022)
  • Step 1: Understand that the radar system can detect objects in a circular area around it.
  • Step 2: Identify the radius of the area. The radius (r) is the distance the radar can detect, which is 100 km.
  • Step 3: Use the formula for the area of a circle, which is Area = πr².
  • Step 4: Substitute the radius into the formula. So, Area = π(100 km)².
  • Step 5: Calculate (100 km)², which is 10000 km².
  • Step 6: Multiply by π (approximately 3.14). So, Area ≈ 3.14 * 10000 km².
  • Step 7: Calculate the final area, which is approximately 31415.93 km².
  • Area Calculation – Understanding how to calculate the area of a circle using the formula A = πr², where r is the radius.
  • Units of Measurement – Recognizing and correctly applying units of measurement (e.g., km²) in calculations.
