The area of one jellyfish is pi r squared or 3.14 x 1 squared (the diameter of the jellyfish is 2 feet so the radius is 1 foot) or essentially 3.14 square feet. 2000 x 3.14 = 6280 square feet. The area of the ocean floor is 120 x 360 feet or 43200 square feet. So 6280/43200 is equal to 0.15 or 15%
1/9 of the aquarium was filled with 1/7 liter
1 whole fraction of the aquarium will be filled = 1/7 ÷ 1/9
= 1/7 * 9/1 = 9/7
9/7 liters or 1 2/7 liters will be needed.
