-1/2 = -3/6
-3/6 + 1/6 = -2/6
-2/6 = -1/3
-1/3 is your answer
hope this helps
The formula to get the circumference is 2πr, π being pi and r being your radius.
Your r is 0.9 since the radius is half the diameter.
2πr = 2 x 3.142 x 0.9
= 5.6556cm
≈ 5.7cm
Answer:
true yes sir
Step-by-step explanation:
If vector A⃗ has components Ax and Ay and makes an angle θ with the +x axis, then tanθ = Ay/Ax to get the angle of the vector components. Since the trigonometric function of tanθ is sinθ over cosθ, and since sinθ = y/r and cosθ = x/r.
Unproportional. 60/10=6
90/20=4.5
120/30=4
150/40=3.75
