Answer:
Step-by-step explanation:
Remark
What you don't know and what makes the problem confusing, is that where to the given arcs start and end. So I am going to say that both arcs start from E and 119 ends at D, and 174 ends at F which means that the arc FD is not known, but it is not hard to find.
The total number of degrees from beginning to end is 360 degrees. The formula for finding FD is
Formula
FD = 360 - (174 - 119)
The formula for x is (ED - FD)/2
Solution
Arc FD = 360 - (174 - 119)
Arc FD = 67
So x = (119 - 67) / 2
x = 52 /2
x = 26
Answer: 907.92 ft²
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a circle, which is shown below:

Where r is the radius of the circle.
2. You know the radius of the circle B, therefore, when you susbtitute it into the formula, you obtain that the area of the circle B is:

64 - 9 = 55 \sqrt{55} = 7.4161984871
7.4161984871/2 ≈3.7
