Answer:
1360.7 feet^3
Step-by-step explanation:
radius = diameter / 2 = 9 /2 = 4.5 feet
Volume = radius^2 x pi x height = 4.5^2 x 3.14 x 10.7 = 680.3595 feet^3
the water tanks are two so
total volume = 680.3595 x 2 = 1360.719 feet^3
for round the answer to the nearest tenth, we have to look at the number after 7. If it is smaller than 5 we can leave 7, if it its higher or equal to 5, we have to change 7 in 8. In this case is 1, so it remains 7
Final answer = 1360.7 feet^3

Let x be the no. of seconds it takes for the balloons to be at the same height.
7+3x = 12+2x
Deduct both sides by 2x.
7+x = 12
Deduct both sides by 7.
x = 5
Ans: It will take 5 seconds for the balloons to be at the same height.
First you subtract three from three and -29 then you divide that by -2
