Question

Find the volume of the cone.

12 cm
r = 8 cm
V = [?] cm3
Round to the nearest tenth.
Enter

Answer 1

800

Explanation:

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

`V=\pi 8^(2) (12)/(3) \\V=\pi (64)(4) = 256\pi`

256π = 804.247719319

To the nearest tenth: 800

Answer 2

V = 803.8 cm^3

Explanation:

h = 12cm

r = 8cm

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

V =
`(1)/(3)`
`\pi`
`(8)^(2)` (12)

V = 4
`\pi` (64)

V = 803.84
