Question

PLEASE HELP!!! WILL MEDAL!!!
A spherical model of planet earth has a radius of 3 ft.



What is the approximate volume of the model of planet earth?

Use 3.14 to approximate pi and express your answer in hundredths.



ft3

Answer 1

So i did this... and got 113.1 but should I round since it says 'apporximate'

Answer 2

>>r answer in hundredths.

The answer came out on the exact hundredth.

I think the answer should be 113.04 on the button.

Answer 3

I assume that this is done prior to calculation:

Use 3.14 to approximate pi.

Answer 4

oh so the radius should've been 300? Im confused when you said>>r answer in hundredths.

Answer 5

The radius is 3.

I use >>> to indicate that I am repeating a post made earlier in the thread.

Answer 6

>>r answer in hundredths.

This means I read in the stated problem that the answer should be in hundredths.
I inadvertently copied the r in that.

>> express your answer in hundredths.

The r is from the last letter in "your."

Answer 7

This is what I would put for the answer: 113.04 cubic feet

Answer 8

but can you show me what r answer in hundredths looks like...unless its just 113.04

Answer 9

It is just 113.04.

I did what you did on Wolfram and got that same answer.

Answer 10

cool. :) thank you again :D

Answer 11

You posted this: So i did this... and got 113.1

That answer is to the nearest tenth.

The question says to approximate to the nearest hundredth.

So, you must put 113.04

Answer 12

You are welcome.
