Options:

  1. 154
  2. 144
  3. 138
  4. 160

Correct Answer: 154

Solution: 

Area = π × radius² = (22/7) × 7² = (22/7) × 49 = 154 square meters.

Questions & Step-by-Step Solutions

A circular garden has a radius of 7 meters. What is the area of the garden in square meters? (Use π = 22/7)
  • Step 1: Identify the formula for the area of a circle, which is Area = π × radius².
  • Step 2: Substitute the given radius (7 meters) into the formula: Area = π × (7)².
  • Step 3: Calculate (7)², which is 49.
  • Step 4: Now substitute π with 22/7 in the formula: Area = (22/7) × 49.
  • Step 5: Multiply 22 by 49 to get 1078.
  • Step 6: Divide 1078 by 7 to find the area: 1078 ÷ 7 = 154.
  • Step 7: Conclude that the area of the garden is 154 square meters.
  • Area of a Circle – The area of a circle is calculated using the formula A = π × r², where r is the radius.
