ok well as you see the right side is 32 in and the left side is the exact same as the right side so you add 32 + 32. Now this is the part that gets tricky soo we now know that the bottom is 20 feet so if he cut the dome on the botton in half we would get 20 ft. sooo know we need to find the area of the dome which is 20 ft too since it is the exact same as 20ft so then we add 20 to the number and now add up!
