1. Problem Description

The problem asks us to find the volume of a funnel, which is in the shape of a cone. The radius of the funnel is 6 cm, and the slant height is 10 cm. We need to calculate the volume to the nearest tenth of a cubic centimeter.

2. Solution Steps

First, we need to find the height hh of the cone. We can use the Pythagorean theorem:
r2+h2=l2r^2 + h^2 = l^2, where rr is the radius, hh is the height, and ll is the slant height.
62+h2=1026^2 + h^2 = 10^2
36+h2=10036 + h^2 = 100
h2=10036h^2 = 100 - 36
h2=64h^2 = 64
h=64h = \sqrt{64}
h=8h = 8
Now that we have the height h=8h = 8 cm and the radius r=6r = 6 cm, we can find the volume of the cone using the formula:
V=13πr2hV = \frac{1}{3}\pi r^2 h
V=13π(62)(8)V = \frac{1}{3}\pi (6^2) (8)
V=13π(36)(8)V = \frac{1}{3}\pi (36) (8)
V=13π(288)V = \frac{1}{3}\pi (288)
V=96πV = 96\pi
Now we approximate the value of π3.14159\pi \approx 3.14159:
V96×3.14159V \approx 96 \times 3.14159
V301.59264V \approx 301.59264
Rounding to the nearest tenth of a cubic centimeter, we get 301.6301.6 cm3^3.

3. Final Answer

301.6 cm3^3
