Arain barrel is a right circular cylinder. if 1ft^3 =7.5 gallons, how many gallons of rainwater can the barrel hold?
use 3.14
barrel is 1.35ft left to and 5ft top to bottom.

so, converting firstly the mixed fractions to improper fractions and then "adding".

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
