Answer: the cylindrical bottle contains 141.39 centimeters ^3 of water
Explanation:
The bottle has the shape of a cylinder. This means the volume of the bottle will be calculated using the formula for calculating the volume of a cylinder. Formula for calculating the volume of a cylinder is
V = πr^2h
Radius, r = diameter of the cylindrical water bottle /2 = 4/2 = 2 centimeters
Height of cylindrical water bottle, h = 15 centimeters
Volume of cylindrical water bottle, V = 3.142 × 2^2 × 15
= 188.52 centimeters ^3
If he filled the water bottle 3/4 full of water, this means that the current volume of the water bottle is 3/4 × it's original volume.
= 3/4 × 188.52 = 141.39 centimeters ^3
