The answer is 173 ft²
The area of the patio (A) is half of the area of the circle (A1) with a diameter of 21 ft:
A = A1/2
The area of the circle with radius r is:
A1 = π * r²
π = 3.14
We do not have the radius, but we know that it is a half of the diameter:
r = 21 ft / 2 = 10.5 ft
A1 = 3.14 * (10.5)² = 346.18 ft²
So, the area of the patio is:
A = A1/2
A = 346.18 ft² / 2
A = 173.09 ft² ≈ 173 ft²

12 / 6 = 2
2 + 4 = 6
6 / 3 = 2
so the answer is 2
Answer:
13a² + 5
Step-by-step explanation:
Not 100% but 90% sure. Work on Picture.
The sum of the interior angles can be represented by:
180(n-2)
180 x 2 = 360
Therefore, the sum of the angles must be 360.
56 + 97 + 136 = 289
360 - 289 = 71<span>°
