(3x-4)(3x-4) not sure if this is correct
Answer:
Step-by-step explanation:
Considering the expression
Therefore,
Take that pi = 3.142
pi r = 9.42
r = 9.42/3.142 = 2.998
d = 2 x 2.998 = 5.996
Cricumference = 3.142 x 5.996 = 18.839 cm
You need to get the radius then multiply by 2 to get the diameter then you can get the circumference.
Refer to the figure below.
The reference angle is 360 - 275 = 85°.
Note that cosine is positive but sine is negative in the 4th quadrant.
Therefore,
the x-component of the vector is
16.3 cos(85°) = 1.4206
the y-component of the vector is
-16.3 sin(85°) = -16.238
Answer: (1.42, -16.24)
