Let r be a radius of a given circle and α be an angle, that corresponds to a sector.
The circle area is

and denote the sector area as

.
Then

(the ratio between area is the same as the ratio between coresponding angles).

.
Area = Length x Width
so, 88 = (something) x 8
Can you work out the something using mental math?
That would be 400 / 28 = 14.29 gallons to nearest hundredth
