Answer 5

Find the volume of a sphere with a radius of 10 feet. Round to the nearest whole number.
1,257 ft3
4,187 ft3
1,089 ft3
1,568 ft3

Okay, so the formula for the volume of a sphere is:

\(V = \dfrac{4}{3} \pi r^3\)

Plug in what we know:

\(V = \dfrac{4}{3} (3.14)(10^3)\)

Can you multiply 4/3 * 3.14?

Answer 6

Real quick, is that a test and youare looking to cheat? If you're not cheating I could possibly answer some of these

Answer 7

@Vanquish If by 'answer' you mean 'give him the answer' we are not here to do that..we have to guide them to the answer, and we need their participation.

Answer 8

@Vanquish is a quick chek

Answer 9

Answer 10

its ok :) @Vanquish

Answer 11

Yes, it's perfectly fine as you are new.

Answer 12

Now, can you multiply 4/3 * 3.14? @bmo1345

Answer 13

how do u * a fraction on the calculator? @iGreen.

Answer 14

Google works, but First you divide 4 / 3

Answer 15

Then you multiply 3.14

Answer 16

4.18....

Answer 17

Yes, now multiply by 10^3, which is 1000

What's 1000 * 4.18?

Answer 18

10^3 is 30

Answer 19

No, it's 1000.

\(10^3 \rightarrow 10 \times 10 \times 10\)

Answer 20

but 1000* 4.18= 4180.0

Answer 21

Yes, but when you multiplied 4/3 * 3.14, the actual result is:

4.18666667

And 4.18666667 * 1000 = 4186.666667 And it says to round to the nearest whole number so we have:

4187

Answer 22

so #2 is B

Answer 23

Yes.
