Question

For spring break this year your family decided to visit Michigan, but it snows the first weekend you are there. You decide to make a snowman. If the bottom ball is 3 feet across, the middle ball is 2 feet across, and the top is 1 foot across, how much snow is needed to build the whole snowman? Round your answer to the nearest cubic foot.

A)19 cubic feet of snow

B)31 cubic feet of snow

C)511 cubic feet of snow

D)824 cubic feet of snow

Answer 1

Okay, you need to find the volume of each of the balls then add them together.. do you know how to do that?

Answer 2

um 4/3\[\pi\]r^3

Answer 3

Yes! the volume of a sphere is\[V=\frac{ 4 }{ 3 }\pi r^3\] so what are the lengths of each of the radii?

Answer 4

hold on

Answer 5

okay :)

Answer 6

ok srry i had to commute to schoolwith no connection

Answer 7

Oh, it's okay. So, what are the lengths of the radii?

Answer 8

.52, 4pi/3,14.13

Answer 9

lol i was thinking the same thing hold on

Answer 10

those r the volumes of each

Answer 11

Ohhh. okay. let me check.

Answer 12

How did you get those? What did you use for pi?

Answer 13

(srry im on my phone so no symbols) i used 4/3(pi)(r)^3

Answer 14

and divided the feet across to get the radius

Answer 15

So, for the radii, you got .5, 1, and 1.5, right?

Answer 16

yes

Answer 17

Okay... there's only one problem. Don't leave the second volume in terms of pi, like you did. Then you just need to add all of them together to find your answer.

Answer 18

oh ok i get ya

Answer 19

Okay. Let me know what you get. :)

Answer 20

ok i get 18.84

Answer 21

okay good :) so, which answer does that round to?

Answer 22

to A thanks! srry i canf give a medal right now cuz im on my phone but if i could i would give you 50 ;)

Answer 23

No problem. :)
