It's my BIRTHDAY!! So, for my birthday gift, can someone answer this quick and show me how you got the answer! TYSM!!! Btw, this is math. (20 POINTS!)

Built in 1599, the Globe Theatre was home to William Shakespeare and his performing company, The Lord Chamberlain’s Men. It was a circular amphitheater that stood 3-stories tall and had a diameter of 100 feet. What formula can you use to calculate the area of the theatre? (Make sure to use Pi if needed)
