WebRemember that the perimeter is the distance round the outside. The perimeter of a semicircle is half of the circumference plus the diameter. \[Circumference\, of\, circle=\pi … WebFor a semicircle with a diameter of a + b, the length of its radius is the arithmetic mean of a and b (since the radius is half of the diameter). The geometric mean can be found by dividing the diameter into two segments of lengths a and b, and then connecting their common endpoint to the semicircle with a segment perpendicular to the diameter.
