- The circumference of a circle = 2I r = I a (where a is the base of the semicircle and is also the diameter of the circle) The perimeter of the semicircle = half the per … imeter of the circle + the base length The perimeter of the semicircle = I a/2 + a = a(1 + I /2) feet
- 5/11/2011 · Best Answer: to find out the area of the semi circle multiply the radius squared by pie (3.14) and then divide by 2. I you have the diameter halve that to get the radius. perimeter is known as circumference on circles and you get that by multiplying pie and the radius and doubling the answer.
