Answer:
First, we need to find the radius of the cylinder.
The circumference of the cylinder is given as 87.92 cm.
Circumference = 2πr
87.92 = 2πr
r = 87.92 / (2π) = 13.993
Now, we can use the formula for the volume of a cylinder to find the volume of the water tank:
Volume = πr^2h
Volume = 3.14 x 13.993^2 x 160
Volume ≈ 97729.25 cm^3
Rounding to two decimal places, the volume of the water tank is approximately 97729.25 cm^3.
