|dw:1347415453405:dw| can someone tell me where i went wrong??

this is not wrong
@demitris you get the same ans!
i agree with demitris ..he is right
i did integrate over 0 to R and got the answer I stated above. but it's wrong for some reason and i have no idea why.
this is an online assignment and i entered the answer a couple times and it kept saying it's wrong and to try again.
