the volume of a tank that is 2'- 0'' in diameter and 6'
-0'' long is _ cu ft. ???? please help
V = pi * r^2 * h
V = 3.14 * 6
V = ?
985.96 is this correct
No.
What do you get when you multiply 3.14 times 6?
18.84
Right. The volume is 18.84 cubic feet.
To find the volume of a tank, you need to use the formula for the volume of a cylinder, which is V = πr^2h, where V represents the volume, π is a constant approximately equal to 3.14159, r is the radius of the tank, and h is the height of the tank.
In your case, the diameter of the tank is given as 2 feet. Since the radius is half the diameter, the radius would be 1 foot.
However, the height of the tank is given as 6 feet - 0 inches. To calculate this in feet, you need to convert the inches to feet. In this case, there are 12 inches in 1 foot. So, the height would be:
6 feet + (0 inches / 12 inches per foot) = 6 feet + 0 feet = 6 feet.
With the radius (r) as 1 foot and the height (h) as 6 feet, you can now calculate the volume (V) of the tank using the formula:
V = πr^2h
V = 3.14159 × 1^2 × 6
V = 3.14159 × 1 × 1 × 6
V = 3.14159 × 6
V ≈ 18.84954 cubic feet
Therefore, the volume of the tank is approximately 18.84954 cubic feet.
