To calculate the volume of a paper cone cup, we can use the formula for the volume of a cone:
\[
V = \frac{1}{3} \pi r^2 h
\]
Where \( V \) is the volume, \( r \) is the radius of the base of the cone, and \( h \) is the height of the cone.
From the dimensions you've provided, it seems you have a height \( h = 9 \) cm, but you haven't specified the radius \( r \). However, if we assume that the diameter of the base is equal to the height (which is a common approximation), then the radius \( r \) would be half of the diameter.
Let's assume the diameter is also 8 cm, which would make the radius \( r = \frac{8}{2} = 4 \) cm.
Now, let's calculate the volume:
\[
r = 4 \, \text{cm}
\]
\[
h = 9 \, \text{cm}
\]
Substituting those values into the volume formula:
\[
V = \frac{1}{3} \pi (4)^2 (9)
\]
\[
V = \frac{1}{3} \pi (16)(9)
\]
\[
V = \frac{1}{3} \pi (144)
\]
\[
V = 48\pi \, \text{cm}^3
\]
To get a numerical value, we can approximate \(\pi\) as 3.14:
\[
V \approx 48 \times 3.14 \approx 150.72 \, \text{cm}^3
\]
Thus, the cone cup can hold approximately **150.72 cubic centimeters of water**. If you meant different measurements, feel free to provide them, and I can recalculate accordingly.
