Given the formula for circumference is
X=43/12 If you need work shown please tell me in the comments. Also please mark me as brainliest.
I dont think its possible to be 5 inches
also it depends on the time of day
6 feet * 7 feet = 42 feet²
18 feet * 21 feet = 378 feet²
42 feet² was painted for $52
1 feet² will be painted for $52/42
378 feet² will then be painted for: ($52/42) * 378
= $468
Hence 18 feet by 21 feet will be painted for $468
Hope this helps.
