The circumference of a circle whose diameter is 7 inches is approximately:

  • (A) 22 inches
  • (B) 28 inches
  • (C) 38 inches
  • (D) 54 inches
  • Solution: The formula used to calculate the circumference of a circle is C = πd, where d represents the diameter.
  • So, if we consider a circle whose diameter is d = 7 inches, the formula would be: C = πd = (22/7)d = (22/7) ×7 = 22 inches
  • Answer: 22 inches, i.e., option A.
