Question

Geometry help please

Answer 1

Hello!

The equation to find the volume of a cone is


`V = \pi r^(2) (h)/(3)`

v is volume
r is radius
h is height

Put in 3.14 for pi and the numbers we know


`V = 3.14 * 8^(2) (16)/(3)`

Square the 8


`V = 3.14 * 64 (16)/(3)`

multiply 64 by 3.14


`V = 200.96 * (16)/(3)`

Multiply

V = 1071.78

We round to the nearest tenth

V = 1071.8

The answer is 1071.8 cubic inches

Hope this helps!

Answer 2

Volume of a cone:


`V = (1)/(3) \pi r^2 h`

where
V = volume
r = radius of the base
h = height of the cone

In this case, r = 8 in., and h = 16 in.


`V = (1)/(3) \pi r^2 h`


`V = (1)/(3) * 3.14 * (8~in.)^2 * 16~in.`


`V = 1071.8~in.^3`
