Im good, thanks.

jagr2713 (jagr2713):

@IMStuck @Dbzfan836 can u help

OpenStudy (dbzfan836):

yes, but can you seprately type or take a picture of the penny problem?

jagr2713 (jagr2713):

i already did the 3challenges all i need is the questions

OpenStudy (dbzfan836):

I only needed the first picture, and the first challenge pic, which I found. What is the volume of the jar [a cylinder] that is 6 in. wide and 11.5 in. high?

jagr2713 (jagr2713):

1. First to find the volume of a penny you us the formula “3.14*r2*h” and plug .75 and .61 in it and get 3.14*.75/2)^2*.61 and get 0.0269. First we use the formula 3.14XR^2XH. So b/c the diameter is 6 you divide and get 3 and put in formula 3.14*3^2*11.5. I got 324.99 and I round and got 325. Then you divide 325 and 0.0269 and I got 12081.

jagr2713 (jagr2713):

thats what i did

OpenStudy (dbzfan836):

for the jar, you are very, very off

jagr2713 (jagr2713):

my answer?

OpenStudy (dbzfan836):

yes, The width is diameter, not radius, so the radius is 3 in.

OpenStudy (dbzfan836):

replace the width with the radius, and you have your answer.

OpenStudy (dbzfan836):

It's volume is about 124.99, or 125in^3

OpenStudy (dbzfan836):

same with the pennies. replace diameter with radius.

OpenStudy (dbzfan836):

@-StudyShark- do not give out the answer staightforward, it is cheating

OpenStudy (dbzfan836):

You broke the rules of OS, @-StudyShark-

jagr2713 (jagr2713):

so number one of the questions is one is 124.99 so whats the other part of the question

OpenStudy (dbzfan836):

@jagr2713 , 1: the challenge #1 you did was wrong. 2: The t=other part I need is the pennies' actual volume

jagr2713 (jagr2713):

so can you how the problem you did you challenge one

jagr2713 (jagr2713):

igtg really soon can you just like give me the answers for the 1-5 questions and i will figure it out later

OpenStudy (dbzfan836):

I dont have answers yet, and I won't be availible tomorrow, so yeah, youll need another person to help

OpenStudy (dbzfan836):

So bye

jagr2713 (jagr2713):
