Answer:
39.275
Step-by-step explanation:
the diameter of the semicircle is 10
A semicircle is half a circle, and a quarter circle is 1/4 of a circle.
Perimeter of a semicircle is ¶d/2
= 3.142 x 10/2 = 3.142 x 5 = 15.71
For 2 semicircles that will be 15.71 x 2 = 31.42
For the quarter circle, perimeter is ¶d/4 = 3.142 x 10/4 = 3.142 x 2.5 = 7.855
Total perimeter = 31.42 + 7.855 = 39.275
I think it is 432.sorry if it is wrong though. My bad calculation error.
Answer:
I cant see good
Step-by-step explanation:
A) 45%, (100-200)/200=0.45 which also equals 45% :)
You use elimination the get x=5 and then plug it in to get y=0 so the coordinate is (5,0)
