13,000,000 is the answer.
Radius of flower bed (r) = 4 ft

= 3.14
Area of flower bed (A) =

r² = 3.14 x 4² = 50.24 ft²
Any fraction that is greatwer than 1/1 in simplest form
Since you know that the top angle is 90 degrees and the bottom is 45 that tells you that the only other angle has to be 45 degrees which means the side it opens up into is also 3radical2 so then you do a^2+b^2=c^2 and you get 4radical3
