C=2πr and the circumference is measured at 360°
So if we were to set up a proportion we could say:
s/(2πr)=α/360
α=180s/(πr)
We are given that s=4m and r=13m so:
α=180(4)/(13π)
α=720/(13π) m which is approximately:
α≈17.63°
Which is why radians are often used, because in radians...
α=[720/(13π)](π/180)
α=4/13 rads
Or the arc length in radians is simply expressed as:
s=rα
α=s/r (which is much neater :P) then it is plain to see that:
α=4/13 rads
Answer:
The answer is 853
Step-by-step explanation:
22392 - 1920 after you do the minus you should divide the answer Answer ÷ 24
Answer:
76,800
Step-by-step explanation:
This is because 808 is closer to 800
#1 is x3
Bc x goes up 3 each time and y goes up 2 each time
Answer:
-8x + 5y + 4
Step-by-step explanation:
- 6x + 5y - 2x + 4 Group like terms
-6x - 2x + 5y + 4
= - 8x + 5y + 4
