Step-by-step explanation:
the length <em>s</em><em> </em>of the arc AC is given as :
s = r. 0
where
r = 10 is radius
0 = 90°
= π/2 rad is angle
s = 10. π/2
= 5π
= 5.3.14
= 15.7 ~ 16
Answer:
(7,7)
Step-by-step explanation:
Well, if you're following PEMDAS (Parentheses, Exponents, Multi/Div, Add/Sub), yes, first you would multiply 4x2, then since it's all adding and subtracting, you would go left to right, so if I'm right..
5-8+8-1 is the equation you'd need. So..
5-8=-3 -3+8=5-1=4. If I'm right, then 4 is your total. Hope that helped!
