diameter = 12 ft
Area = π r²
r = radius. It is 1/2 of the diameter.
r = 12 ft / 2 = 6 ft.
Area = 3.14 * (6ft)²
A = 3.14 * 36ft²
A = 113.04 ft² or 113.0 ft² rounded to the nearest tenth.

Amount of water=0.7 * 130 pounds=91 pounds.
answer: 91 pounds of water.
Final answer:
Given that the human body is about 70% water, a person who weighs 130 pounds would carry about 91 pounds of water weight.
Explanation:
The question is asking us to calculate the amount of water by weight in a human body. We can solve this by using a percentage (or a decimal equivalent) and multiplying that by the person's total weight. Given that 7/10 (or 70%) of the human body is water and the person weighs 130 pounds, we simply multiply 130 by 0.7 (the decimal equivalent of 7/10).
To calculate: 130 pounds * 0.7 = 91 pounds. Therefore, about 91 pounds of a person who weighs 130 pounds is water.

Answer:
250 litters
Step-by-step explanation:
To solve this question, we first need to know the conversion from cubic meter to liter.
1 cubic meter is equal to 1000 liters.
So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:
1 m3 -> 1000 L
1/4 m3 -> x L
x * 1 = (1/4) * 1000
x = 1000 / 4 = 250 L
So we need 250 liters of water.
