Best ResponseYou've already chosen the best response.0\[V = \frac{ 4 }{ 3 } \pi r^3\] Use 3.14 for pi and r is 1/2 of the diameter.

Best ResponseYou've already chosen the best response.0As explained earlier, radius is 1/2 of the diameter. So what would it be?

Best ResponseYou've already chosen the best response.0to get to the nearest hundredth means to 2 decimal places calculate to 3 places. if the 3rd is 5 or more add 1 to the 2nd place. if the 3rd place is less than 5 drop it

Best ResponseYou've already chosen the best response.0Well, I won't give you the answer, but I'll help you get it for yourself. Back to my earlier question. What did you get for the radius?

Best ResponseYou've already chosen the best response.0Recall that the radius is 1/2 of the diameter and the diameter is given as 2.5 cm. So, what is 1/2 of 2.5 cm?

anonymous

Best ResponseYou've already chosen the best response.0Nope. Divide 2.5 by 2. What do you get?

Best ResponseYou've already chosen the best response.0That's correct. So r = 1.25 cm. Now the volume is calculated using\[V = \frac{ 4 }{ 3 } \times 3.14 \times \left( 1.25 \right)^3\]Are you able to do this calculation?

Best ResponseYou've already chosen the best response.0Won't tell. If you just want someone to give you the answer, I'm the wrong guy. The problem is all done except for the final calculation, which you said you could do. So, what do you get?
