The answer would be (0,-2)
Answer:
V≈15927.87 in³
Step-by-step explanation:
The volume of a cylinder is found by multiplying the area of its top or base by its height and is defined as: V = π*r²*· h
You cannot round 23 to the nearest thousand.
There are only TWO PLACE VALUES in 23: ones and tens.
Cos(A-B) = cosAcosB + sinAsinB
<span>
cos(</span>π/2 - θ) = cos(π/2)cosθ + sin(π/2)sinθ
π/2 = 90°
cos(π/2) = cos90° = 0. sin(π/2) = sin90° = 1
cos(π/2 - θ) = cos(π/2)cosθ + sin(π/2)sin<span>θ
</span>
= 0*cosθ + 1*sin<span>θ = </span>sin<span>θ
Therefore </span>cos(π/2 - θ) = sin<span>θ
