Cos ( theta ) = cos 7π/6 = -√3/2
sin ( Theta ) = sin 7π/6 = -1/2
Coordinates of the terminal points are: ( -√3/2, -1/2 )
A different way to do this is doing adding
1.) 3/4 + 3/4 + 3/4 + 3/4 = 12/4 = 3
Another way is reducing
12/4 = 3
I hope this helps
Diameter is 13
radius is 6.5
circumference is 13pi or 40.84
area is 42.25pi or 132.732
So,
Matt answered 20 out of 25 questions.

We need to get the denominator to be 100. We can do that by multiplying the fraction by a form of 1.

From here, it should be easy to see that Matt has answered 80% of his test.
<em>THE CORRECT ANSWER IS 57 CM³</em>
