The third angle is 29 degrees.
180 - 58 - 93 = 29
I believe the answer would be 3/40
If the diameter is 30 ft then the area of the circle is 706.5 you can approximate it if you want and you will have 707.
P would equal 98 i believe because since you are dividing p by 7 you would have to do the reverse to get p by itself which would be p=14*7 or p=98
