How many gallons in a 6' diameter x 7'-4 deep cylinder?

Answer 1

1 cu ft ≈ 6.22884 imp gal ≈ 7.48052 US gal

12 in = 1 ft

→ 7'4'' = 7+4/12 ft = 7⅓ ft

→ volume = area base × height

= π × (6 ft ÷ 2)² × 7⅓ ft

= 66π cu ft

≈ 66π × 6.22884 imp gal ≈ 1292 imperial gallons

≈ 66π × 7.48052 US gal ≈ 1551 US gallons

Answer 2

It is 1292 Imperial gallons.
