Given:
8 tiles
radius from the center of the archway to the inner edge of the tile. 7 ft.
radius from the center of the archway to the outer edge of the tile. 8 ft = 7 ft + 1 ft.
Area of a semi circle = π r² / 2
A = (3.14 * (7ft)²) / 2 = (3.14 * 49ft²) / 2 = 153.86 ft² / 2 = 76.93 ft²
A = (3.14 * (8ft)²) / 2 = (3.14 * 64ft²) / 2 = 200.96 ft² / 2 = 100.48 ft²
100.48 ft² - 76.93 ft² = 23.55 ft²
23.55 ft² / 8 tiles = 2.94 ft² per tile.

Step-by-step explanation:
Answer:
A = $6,700(1 +0.0865^t)
APY = 8.65%
Step-by-step explanation:
Daily compounding of interest results in an annual growth factor of ...
gf = (1 +r/365)^365 . . . . for APR = r
Your growth factor is ...
gf = (1 +0.083/365)^365 ≈ 1.086532
Then the growth rate (APY) is ...
APY = gf -1 ≈ 8.65%
The account value is multiplied by the growth factor each year, so after t years will be ...
A = P(1 +APY)^t
A = $6,700(1 +0.0865)^t . . . . . . . 0.0865 is the annual growth rate
