How do you do this physics problem?

he citizens of Paris were terrified during World War I when they were suddenly bombarded with shells fired from a long-range gun known as Big Bertha. The barrel of the gun was 36.6 m long and it had a muzzle speed of 1.48 km/s. When the gun's angle of elevation was set to 50�, what would be the range? For the purposes of solving this problem, neglect air resistance.
