The perimeter of a semicircle consists of the curved part and the straight diameter. The curved part can be calculated using the formula for the circumference of a full circle, which is (C = 2\pi r). For a semicircle, it would be (\pi r), so for a radius of 7 cm, the curved length is ( \pi \times 7 \approx 21.99 ) cm. Adding the diameter (which is (2r = 14) cm), the total perimeter is approximately (21.99 + 14 = 35.99) cm.
