Around 59.69026

Step-by-step explanation:

C = Circumference (What we are looking for)

R = 9.5yd (Radius)

C = 2(Pie [I can't find the symbol])rC = 2(Pie)9.5C ≈ 59.69026

Given:

Radius of the cone = 3 inches

Height of the cone = 8 inches

To find:

The volume of the cone, in terms of π.

Solution:

We know that, the volume of a cone is:

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

Putting r=3,h=8 , we get

$V=\dfrac{1}{3}\pi (3)^2(8)$

$V=\dfrac{1}{3}\pi (9)(8)$

$V=\dfrac{72}{3}\pi$

$V=24\pi$

Therefore, the volume of the cone is $24\pi$ .
