Answer:
B) 20 degrees
Step-by-step explanation:
Arc length = fraction of the circle * circumference
Arc length = fraction of the circle * 2 * pi *r
pi = fraction of the circle * 2 * pi *9
pi = fraction of the circle *18 pi
Divide each side by 18pi
pi
-------- = fraction of a circle
18 pi
1/18 = fraction of a circle
A circle is 360 degrees
1/18 = x/360
Multiply by 360 on each side
360/18 = x
20=x
The answer is two times of square root of 8
You can divide this image into 2 different shapes and there are multiple ways to do this. I drew a line straight down from the side that has a length of 6 to divide the image into 2 rectangles
I now have a rectangle that has sides of 7 and 10 and a rectangle that has sides of 4 and 8
A=L*W so A=7*10 which is 70
A=L*W so A=4*8 which is 32
add these areas together to get 102 so "C" is the correct answer
