" COVERAGE: Spray distance max: 20.5 ft / 5284 sq ft coverage area" No way that number is correct. Either the spray distance is wrong or the coverage area is. Because a 20.5 ft radius would yield a 1320 sq ft area, not 5284. Looks like someone doubled the radius, THEN squared it. A radius of 41ft does yield a 5284 sq ft area.

I’m told by someone that recalls math stuff better than me…
Customer’s math is correct. 1320 sqft
Area = πr²
Square the radius: 20.5 ft * 20.5 ft = 420.25 ft².
Multiply by pi: 3.14 * 420.25 ft² = 1319.685 ft².
