Step-by-step Solution for Part-a:
<u>We know that:</u>
- Row-1: 20 seats
- Row-2: 20 + 11
- Row-x: 20 + (11x - 11)
Since the number of rows in rows x is 20 + (11x - 11), the formula to calculate the number of seats in each row is 20 + (11x - 11).

Step-by-step Solution for Part-b:
<u>We know that:</u>
- y rows = 174 seats
- Obtained rule from part-a: 20 + (11y - 11)
<u>Solution:</u>
- 20 + (11y - 11) = 174 rows
- => 20 + 11y - 11 = 174 rows
- => 9 + 11y = 174 rows
- => 11y = 174 - 9 rows
- => 11y = 165
- => y = 165/11
- => y = 15
Hence, the row which has 174 seats is row 15.

Answer:
Step-by-step explanation was 34
Answer:
C) 26π mi
Step-by-step explanation:
1. Find the diameter:
<em>24² + 10² = d²</em>, because of the pythagorean theorem.
Add: 676 = d²
Square root: <em>26 = d</em>, no negatives by domain
2. Find the circumference:
<em>C = dπ</em>
Plug in: C = 26π miles
