A snowcone with a radius of 4 cm is sold in a cone-shaped paper cup with a height of 12 cm and an opening 6 cm wide.
If all the ice melted in the cup, would it overflow?
you mean the snow is a 4cm sphere? If so, then compare
4/3 π*4^3 vs 1/3 π*3^2*12
I think the snow forms into the shape of the cone shaped paper cup. but i don't think it would overflow if melted
To determine if the snowcone would overflow when it melts, we need to compare the volume of the melted snowcone with the volume the paper cup can hold.
Step 1: Calculate the volume of the snowcone.
The volume of a cone can be calculated using the formula:
V = (1/3) * π * r^2 * h
where V is the volume, π is a mathematical constant approximately equal to 3.14, r is the radius of the cone, and h is the height of the cone.
Given:
Radius (r) of the snowcone = 4 cm
Height (h) of the snowcone = 12 cm
Using the formula, we can calculate the volume of the snowcone:
V_snowcone = (1/3) * 3.14 * (4^2) * 12
Step 2: Calculate the volume of the paper cup.
The volume of a cone-shaped cup can also be calculated using the same formula.
Given:
Radius (r) of the cup = 6 cm (since the opening is 6 cm wide)
Height (h) of the cup = 12 cm
Using the formula, we can calculate the volume of the cup:
V_cup = (1/3) * 3.14 * (6^2) * 12
Step 3: Compare the volumes.
If the volume of the snowcone (V_snowcone) is less than or equal to the volume of the cup (V_cup), then the snowcone will not overflow when it melts. However, if the volume of the snowcone exceeds the volume of the cup, it will overflow.
Now we can compare the volumes:
V_snowcone = (1/3) * 3.14 * (4^2) * 12
V_cup = (1/3) * 3.14 * (6^2) * 12
By calculating the values, we can determine if the snowcone would overflow or not.
To determine whether the snowcone would overflow when it melts, we need to compare the volume of the snowcone to the volume of the cone-shaped paper cup.
First, let's find the volume of the snowcone. The formula to calculate the volume of a cone is given by V = (1/3) * π * r^2 * h, where V is the volume, π is pi (approximately 3.14159), r is the radius, and h is the height.
Plugging in the values for the snowcone, we have V_snowcone = (1/3) * π * 4^2 * 12.
V_snowcone = (1/3) * 3.14159 * 16 * 12.
V_snowcone ≈ 201.06192 cm^3.
Next, let's calculate the volume of the cone-shaped paper cup. The formula for the volume of a cone is the same as the one we used for the snowcone.
Plugging in the values for the cone-shaped paper cup, we have V_cup = (1/3) * π * (6/2)^2 * 12.
V_cup = (1/3) * 3.14159 * 9 * 12.
V_cup ≈ 113.09734 cm^3.
Now, let's compare the volumes. If the volume of the snowcone is less than or equal to the volume of the cone-shaped paper cup (V_snowcone ≤ V_cup), then the snowcone will not overflow when it melts. Otherwise, if the volume of the snowcone is greater than the volume of the cone-shaped paper cup (V_snowcone > V_cup), then the snowcone will overflow when it melts.
Comparing the volumes, we have:
201.06192 cm^3 ≤ 113.09734 cm^3.
Since the volume of the snowcone is greater than the volume of the paper cup, the snowcone would overflow when it melts.
