Answer 2

okay so the Formula is v=4/3*pi*Radius squared so v=3/4*3.14*4^2

Answer 3

but its cubed

Answer 4

i meant cubed sorry

Answer 5

okay so the Formula is v=4/3*pi*Radius cubed so v=3/4*3.14*4^3

Answer 6

but how do i put that in my calculator i only have squared

Answer 7

do you have a ^ sign on your calculator?

Answer 8

no I have y*x

Answer 9

If you have a scientific calculator it would look like dis lol

Answer 10

well i believe your computer has a calculator does it not?

Answer 11

yes

Answer 12

It's very easy to obtain wrong answers on a calculator unless you know and follow "Order of Operations" rules.

If you have v=4/3*pi*Radius cubed

a better way of writing that, for maximum clarity, would be \[V=(4/3)\pi*r^3\]

Answer 13

or\[\frac{ 4 }{ 3 }\pi*r^3\]

Answer 14

thanks

Answer 15

First, divide 3 into 4 AND PRESS "ENTER" This forces your calculator to calculate 4/3 and to hold it in memory.

Answer 16

Next, multiply your result by pi.

Answer 17

can you hlp with more plz
