Question

A spherical water balloon has a radius of 6 inches. How many cubic inches of water will it hold?

a. 288ð in.3
b. 78ð in.3
c. 216ð in.3
d. 144ð in.3

Answer 1

\[V_{\text{sphere}} = \frac{4\pi r^3}{3}\]

Answer 2

@Hero
I got 904.7808

Answer 3

What does this symbol mean? ð

Answer 4

pi I suppose.

Answer 5

I got the same volume formula and my volume on the windows calculator was \(904.7786842338604526772412943845\) using its estimation of \(pi\). The exact answer is \(288\ \pi\).

Answer 6

288 pi = 904.7808

Answer 7

And so I agree with @Hero again.

Maybe it was just an issue with the computer code. I don't see why anyone would substitute a symbol for \(\pi\) if that's what that means.

Answer 8

And the units are \([\text{in.}^2]\)

Answer 9

So, that looks right..

Answer 10

cubic is in^3

Answer 11

Thank you so much I get it now! =)

Answer 12

:)

Answer 13

Pfft, \([\text{in}^3]\), you're right again.
