Questions & Step-by-Step Solutions

If the radius of a circle is 7 cm, what is its circumference? (Use π ≈ 3.14)
  • Step 1: Identify the formula for the circumference of a circle, which is Circumference = 2πr.
  • Step 2: Substitute the value of π with 3.14 in the formula.
  • Step 3: Substitute the radius (r) with 7 cm in the formula.
  • Step 4: Calculate 2 × 3.14 × 7 cm.
  • Step 5: Perform the multiplication: 2 × 3.14 = 6.28.
  • Step 6: Now multiply 6.28 by 7 cm to get 6.28 × 7 = 43.96 cm.
  • Circumference of a Circle – The circumference of a circle is calculated using the formula C = 2πr, where r is the radius.
