To find the circumference and area of a circle with a radius of 5 cm, you can use the following formulas:

  1. Circumference (C) = 2 * π * r
  2. Area (A) = π * r²

Where:

  • π (pi) is approximately 3.14.
  • r is the radius of the circle.

Using these formulas:

  1. Circumference:
    C = 2 * π * 5 cm ≈ 2 * 3.14 * 5 cm ≈ 31.4 cm

  2. Area:
    A = π * (5 cm)² ≈ 3.14 * 25 cm² ≈ 78.5 cm²

So, the correct values for a circle with a radius of 5 cm are:

  • Circumference: 31.4 cm
  • Area: 78.5 cm²

Thus, the correct chart is:

Radius | Circumference | Area
5 cm | 31.4 cm | 78.5 cm²
