Answer:
Option D = 16π/3 ft
Step-by-step explanation:
Arc length formula is written Mathematically as:
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
So, the arc length is 16π/3 ft
The degrees stay the same.
Multiply the decimal by 60
0.39 x 60 = 23.4
Now take the decimal bit and mulitply by 60 to get the seconds.
0.4 x 60 = 24.
So the answer is: 40 degrees, 23 minutes, 24 seconds.

Answer:
Step-by-step explanation:
Ok, well the first thing you need to do is make -4/13 have the same numerator as 9/26. Thankfully, 26 is a multiple of 13, so that step is easy:
-4/13 -> -8/26
Then you can add them together with ease.
9/26 + -8/26 = 1/26
Adding a negative number to anything is the same thing as subtracting.
