Final answer:
The expression for the volume of the popcorn container, given the portion removed has a height of 1/3m, and converted to cubic centimeters, is V = 1/3π m³ - 1/9π m³.
Step-by-step explanation:
To create an expression for the volume of the popcorn container, which is a cone with a portion removed, we start with the formula for the volume of a cone, which is V = 1/3πr²h. Since the height of the removed portion is 1/3m, the volume of the removed portion is then 1/3π(m/3)²(1/3)m.
Converting meters to centimeters (since 1 meter = 100 centimeters), we get V = 1/3π(100m/3)²(100/3)m = 1/3π(10000/9)m³. To find the volume of the actual container, we subtract the volume of the removed portion from the total volume of the cone. So, the expression using m that represents the volume in cubic centimeters is V = 1/3π m³ - 1/9π m³.
