First one is equal to thats all i know
The formula, the area for the circles, the semicircles, the area for the quarter circles, and the total area
A for circles=1571
A for semicircles=1571
A for quarter circles=7854
A for all circles= 10995.98
Because those are straight lines, the 46 degrees must be equal to the (2x - 4).
2x -4 = 46.
2x = 46 + 4
2x = 50
x = 50/2
x = 25.
Do the problem 440×7.5 to find your answer
The answer is a! i hope this helps you!
