Answer:

  • 26.376 units
  • 23.236 units
  • 34.54 units
  • 59.66 units

Step-by-step explanation:

The formula for the circumference of a circle is ...

  C = 2πr = πd

  C = 2(3.14)r = 6.28r   or   C = 3.14d

where r is the radius and d is the diameter.

Put the given radius or diameter into the relevant formula and compute the product. The results are all in "units".

  r = 4.2   ⇒   C = 6.28×4.2 = 26.376

  d = 7.4   ⇒   C = 3.14×7.4 = 23.236

  d = 11   ⇒   C = 3.14×11 = 34.54

  r = 9.5   ⇒   C = 6.28×9.5 = 59.66
