If the radius of a semicircle measures 6.3 cm, what is its total perimeter?

Explanation

The perimeter of a semicircle is calculated by adding the length of the curved part (half the circumference of a full circle) and the diameter. Using the formula: Perimeter = π × radius + 2 × radius. Substituting radius = 6.3 cm, Perimeter = (3.14 × 6.3) + (2 × 6.3) = 19.78 + 12.6 = 32.38 cm, approximately 32.4 cm.
