Answer:
Arc length = 9.42 cm
Step-by-step explanation:
First you need the circumference of the circle
r = 6
C = 2* pi * r
C = 2 * 3.14 * 6 = 37.68
To find the length of the arc, we need to know the central angle. IN this case it is 90 degrees (notice the right angle of the triangle).
To find the length of the arc Arc length = (central angle in degrees/360) * C
Arc length = 90/360 * 37.68
Arc length = 9.42 cm
Simplify the following:
7 - 3 (9×2 n + (3 n + 8 n)/(-n))
3 n + 8 n = 11 n:
7 - 3 (9×2 n + (11 n)/(-n))
(11 n)/(-n) = n/n×11/(-1) = 11/(-1):
7 - 3 (9 2 n + 11/(-1))
Multiply numerator and denominator of 11/(-1) by -1:
7 - 3 (9 2 n + -11)
9×2 = 18:
7 - 3 (18 n - 11)
-3 (18 n - 11) = 33 - 54 n:
33 - 54 n + 7
Add like terms. 7 + 33 = 40:
40 - 54 n
Factor 2 out of 40 - 54 n:
Answer: 2 (20 - 27 n)
