b. How many gallons of water are needed to fill the tank? (1 cubic foot = 7.5 gallons)The Giant Ocean Tank at the New England Aquarium is a cylinder that is 23 feet deep and 40 feet in diameter?
v = 蟺r虏h volume of a cylinder
r = 20ft
h = 23ft
v = 蟺(20)虏23
v = 蟺(400)23
v = 9200蟺 ft鲁 this is the volume of the tank
9200蟺 ft鲁 (7.5gal/1ft鲁)
216,770 gallons
hope this helps!!!
