Answer:
B
Step-by-step explanation:
First find the circumference of the circle with radius of 9 inches:
The full angle has 360°, so, to find the length of the arc DE, you can write:
which yields a proportion:
35x2.5=87.5 so 87.5 is the answer
I believe it's half the radius of the circle because the side would equal the radius and the compass is in the middle of the side, right?
Answer: 2 1/3
Explanation:
10 2/6 - 7 5/6
You can make both a fraction by multiplying the denominator by the whole number, and then adding the numerator to that number, and keeping the denominator the same. So, 10*6 = 60 and 60 + 2 = 62 and you keep the denominator as 6, which would make 62/6
7*6 = 42 and 42 + 5 = 47 so 7 5/6 becomes 47/6
10 2/6 is equivalent to 62/6
7 5/6 is equivalent to 47/6
This just makes it easier to look at.
Now you just work through the equation.
62/6 - 47/6 = 15/6
15/6 = 2 3/6 = 2 1/3
