#5) 7.065 sq. ft.
#6) 36 ft
#7) 200.96 sq. ft.
#8) 176.625 sq. ft.

Explanation
#5) Converting 18 inches to feet, 18/12 = 1.5.  The area of the circle would be given by A=3.14(1.5)² = 3.14(2.25) = 7.065 sq. ft.

#6) The radius is 18 inches, so the diameter is twice that:  18*2 = 36 inches.  Converting this to feet, we have 36/12 = 3 feet.  Each stone is 3 feet across.  Laying 12 of them against each other would give us a total length of 12*3 = 36 feet.

#7) The radius of the entire mirror with frame is 20/2 = 10.  The area of the entire mirror with frame is A=3.14(10²) = 3.14(100) = 314 in².
The area of the mirror without the frame is A=3.14(6²) = 3.14(36) = 113.04 in².

The difference between the two will give the area of the frame:
314-113.04 = 200.96 in²

#8) The area of the circular region is given by A=3.14(7.5²) = 176.625 ft²
