The perimeter of the semicircle is 71.98 inches, approx.
The semicircle cannot be covered by any number of inches because an area (in 2-dimensional space) cannot be covered by a length (in 1-dimensional space).

How many inches do you need to cover a 30 inches diameter circle?
What you need is the area of the circle. Area = Pi x r squared where r is the radius. The radius is one-half the diameter so in this case r=15 to square it, multiply it by itself ( 15 x 15 ) so r squared =225 now multiply that by 3.14 . Ans: 706.5 square inches.

How many 16inch by 16 inch tiles would cover a 11ft diameter circle?
16x16 inch tiles are square. If you place them on a circle, the edges will hang off, so we first need to find the size of the largest square that will fit in the circle. The largest square can be made of four isosceles triangles whose equal sides are equal to the length of the radius, so the area of the contained square is 2r2. An 11-foot diameter circle has a radius of 5.5 feet, so the square has an area of 2(5.5)2 = 60.5 square feet, or 60.5 * 122 square inches = 8712 square inches. The 16x16 tiles are 256 square inches, so 8712 / 256 = 34.03125 tiles that fit completely in the circle.
