Question

A cone has a diameter of 24 in. and a height of 10 in.

What is the volume of the cone?

Use 3.14 as an approximation for π. Express your final answer in tenths.

Answer 1

do you know the formula?

Answer 2

The formula for finding the volume of a cone is:
V = Bh

Answer 3

B = area of the base

Answer 4

1/3 π × r^2 × h

Answer 5

Sorry yes. I confused it with the cylinder

Answer 6

or \(πr^2\dfrac{h}
{3}\)

Answer 7

so what do you have as the radius and height?

Answer 8

So it's just:
\[\frac{ B \times h }{ 1/3 }\]

Answer 9

The height is 10. And the diameter 24 divided by 2 gives us the radius of 12.

Answer 10

ok so \(π12^2\dfrac{10}
{3}\)

Answer 11

It equals 40

Answer 12

the whole thing?

Answer 13

\(3.14 * 12^2 = 452.16\)

Answer 14

now multiply \(452.16*\dfrac{10}{3}\)

Answer 15

It equals 1507.2

Answer 16

yes

Answer 17

yea

Answer 18

Thanks everyone!
