If a circle has a radius of 7 cm, what is its diameter?

  1. 7 cm

  2. 14 cm

  3. 21 cm

  4. 28 cm

The correct answer is: 14 cm

The diameter of a circle is determined by the formula that relates it to the radius. The diameter is always twice the length of the radius. In this case, the radius of the circle is given as 7 cm. To find the diameter, you multiply the radius by 2: Diameter = 2 × Radius = 2 × 7 cm = 14 cm. This calculation directly gives the diameter, confirming that the correct answer is indeed 14 cm. Understanding this relationship between the radius and diameter is fundamental in geometry and helps in solving various problems related to circles.
