Question

Jace made a funnel out of a price of paper. The radius of the funnel is 3 and the height is 6 inches. What is the approximate volume of the funnel?

Answer 1

We have that the funnel is like a cone, so we will use the formula to calculate the volume of a cone in order to find the volume of the funnel

$V=\frac{1}{3}\pi r^2h$

where r is the radius and h is the height

In our case

r=3 inches

h=6 inches

we substitute the values

$V=\frac{1}{3}\pi(3)^2(6)$$V=\frac{1}{3}\pi(9)(6)$$V=18\pi=56.55in^3$
