Question

Cone volume, 2 questions. Picture of the questions with diagrams below.

Answer 1

Do you know the formula for area of a cone?

Answer 2

they're both volume, my bad.

Answer 3

Oh, whoops, I had area in my mind from the post haha

Answer 4

Ok, so do you know the formula for volume of a cone?

Answer 5

yeah, i just figured that out. but i do need you to check an area question that I answered if you don't mind

Answer 6

area? ok haha

Answer 7

nope wait volume too lol

Answer 8

ok,so you need that one checked?

Answer 9

If so... technically none of the answers are correct... pi is not involved in the volume of an oblique cone

Answer 10

The volume formula for a cone is \( \frac{bh}{3} \) where \(b\) is the base area and \(h\) is the height.
Since your base is circular then the base area will be \(\pi r^2\) and in this case since the radius is \(10_{cm}\) then \(b = \pi \cdot 10_{cm}^2 = 100\pi_{cm^2}\).
The height is \(16_{cm}\) so:
$$
V = \frac{100\pi_{cm^2} \cdot 16_{cm}}{3} = \frac{1600\pi_{cm^3}}{3}
$$Your aswer is correct =)
