Answer: r = 7 meters
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Volume = 2,769.48 cubic meters
Height = 18 meters
Therefore,
2769.48 = 3.14 × r² × 18
2769.48 = 56.52r²
r² = 2769.48/56.52 = 49
Taking square root of the left hand side and the right hand side of the equation, it becomes
r = √ 49 = 7 meters
.69 kilometers is your answer! This is because .5 plus .19 is .69. .5 is equivalent to .50
Step-by-step explanation:
Use the following ratio:
13 out of the 213 tagged returned
13/213 is estimate of how many fraction returned
proportional, marked/totalmarked≈caught/totalinlake
213/13=total/104
times both sides by 104*13 (cross multiply)
213*104=total times 13
22152=total times 13
divide both sides by 13
