the height h is 8 in and the volume V is 628in%5E3
V=r%5E2%28Pi%29%2Ah
r%5E2=V%2F%28Pi%29%2Ah
r=sqrt%28V%2F%28Pi%29%2Ah%29
r=sqrt%28628in%5E3%2F%283.14%29%2A8in%29
r=sqrt%28628in%5Ecross%283%292%2F%283.14%29%2A8cross%28in%29%29
r=sqrt%28628in%5E2%2F%283.14%29%2A8%29

r=sqrt%28628in%5E2%2F%2825.12%29%29

r=sqrt%2825in%5E2%29
r=5in
