☆Here is the answer to your question⤵

〰〰〰〰〰〰〰〰〰〰〰〰〰〰

Area of circle = pie r^2

So, pie r^2 = 1386

22/7 × r^2 = 1386

22r^2 = 9702.

r^2 = 9702/22 = 441

r = 21 m

So diameter = 2r = 2 × 21 = 42m

Answer 2

area to circle=πr^2
1386=3.147×r^2
1386/3.147=r^2
440=r^2
r=√441
r=21
diameter =2×r
diameter =2×21
diameter=42meters
