Answer :
Final answer:
The length of the row of bricks is 138 meters to the nearest meter.
Explanation:
Step-by-Step Solution
- Write the area formula: A = πr². Here, A = 1,520 m².
- Solve for the radius:
r² = A/π
r² = 1,520 / π
r² ≈ 1,520 / 3.1416 ≈ 484.04
r ≈ √484.04 ≈ 22 meters - Find the circumference:
C = 2πr
C ≈ 2 × 3.1416 × 22 ≈ 138.23 meters - Round to the nearest meter:
138.23 meters rounds to 138 meters.
So, the length of the row of bricks is 138 meters to the nearest meter.
