Answer 1

Crap. Work got cut off. :/

Answer 2

I got
(A) as my answer though.
Not sure IF it's wrong.

Answer 3

Incorrect. (A) is not the answer

Answer 4

GOD DAMNIT. WHY? D:

Answer 5

No need to swear...

Answer 6

Sorry bro.

Answer 7

The volume of a cone is given as:\[V=\frac{ \pi*r ^{2}*h }{ 3 }\]

Answer 8

Everytime I do it I get some number that's not even an option for the problem. :/
But looks like im trying it again. xD

Answer 9

v=pi * r^2 * 17
----------------
3 How do i get the radius? I think that's where im messing it up.

Answer 10

Very good so far. The problem states that base areas are equal for the two shapes, right?

Answer 11

Right.

Answer 12

9 ft.

Answer 13

Ok well the base of the cone is a circle with area = pi*r^2.
So we again need the radius which we cannot get from the picture.

Answer 14

9 ft is not the radius.

Answer 15

We can however find the base area of the pyramid as is it a triangle and does not require a radius.

Answer 16

okay, then what?

Answer 17

The base is 8 ft.

Answer 18

Did you calculate the base area?

Answer 19

8 ft right?

Answer 20

No. 8 ft is not area. It is length...

Answer 21

Nvm, Bro i got 93.46 as my answer. So it HAS to be it. Thanks ! :)

Answer 22

The base of the pyramid is a triangle with are = b*h/2

Answer 23

Correct!

Answer 24

THANKS AGAIN BRO! I found my mistake!
