OpenStudy (shane_b):

A teepee is essentially a cone right?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so what is the fumilu

OpenStudy (anonymous):

?

OpenStudy (shane_b):

The link doesn't get me to the image...can you cut/paste it here?

OpenStudy (anonymous):

V=1/3*pi*r^2*h

OpenStudy (anonymous):

is that how i do it

OpenStudy (shane_b):

To find the volume yes...I can't see what the question says/shows though so I'm only guessing that's what you need.

OpenStudy (anonymous):

The diagram shows the dimensions of a teepee. Find the volume of the building to the nearest cubic unit. Use 3.14 for p.

OpenStudy (anonymous):

sorry

OpenStudy (shane_b):

So if you have the radius and the height just plug them into the formula to solve for V.

OpenStudy (anonymous):

A. 1,780 ft3 B. 1,382 ft3 C. 21,363 ft3 D. 5,341 ft3

OpenStudy (anonymous):

but some how i did the math and i got 7121 ?????

OpenStudy (anonymous):

i dont think i got the right formula =(

OpenStudy (anonymous):

@Australopithecus

OpenStudy (anonymous):

is it (A)????????????

OpenStudy (australopithecus):

Volume of a cone \[\frac{1}{3}\pi r^2 h = V\] Where, h = height of the cone r = radius of the cone

OpenStudy (shane_b):

What are the given dimensions? The formula is right

OpenStudy (australopithecus):

do you not know how to utilize the formula??

OpenStudy (anonymous):

got 1/3*3.14*100*17=A

OpenStudy (anonymous):

or 1779.3333333333333

OpenStudy (shane_b):

Then check your calculator :) The answer is in the list

OpenStudy (shane_b):

Yes, A :)

OpenStudy (anonymous):

thank you some much :)

OpenStudy (shane_b):

Np...and I'm not sure why the answer was rounded up and not down to 1779...who knows.

OpenStudy (anonymous):

lol

OpenStudy (shane_b):

Significant figures I guess

OpenStudy (shane_b):

By the above I mean that the values in the problem must have been limited to 3 significant figures.
