Diameter = 80/pi feet
First, calculate the weight of 1 coin: 388g / 80 coins = 4.85g. Then, multiply this weight by the number of coins to find the total weight: 4.85g/coin * 10000 coins = 48500g. Therefore, 10000 one rupee coins weigh 48500 grams.
The diameter is about 25.464 units.
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
Circumference of a circle = π × diameter = π × 80 mm = 80π mm ≈ 251 mm
25.464
The field of view would be 80 times the diameter.
