THe area of the whole circle is pi r^2 = 6^2 * pi = 36pi
There are 360 degrees in a crcle so this sectors area i (30/360) *36pi
= 3 pi
Here are the steps to solving:
1) Write out problem 3.6+7.2k <25.2
2) Subtract 3.6 7.2k <21.6
3) Divide by 7.2 k <3
So k<3 would be your answer
A^+B^2 =C^2
6^2 + 1^2 = 37
Square root of 37= 6.08
Rounded to 6.1
Answer 6.1
Opposite side length = 9
Adjacent side length = 12
Hypotenuse side length = 15
sin∅ is found with (opposite/hypotenuse). Therefore, sin∅ = 9/15.
cos∅ is found with (adjacent/hypotenuse). Therefore, cos∅ = 12/15.
tan∅ is found with (opposite/adjacent). Therefore, tan∅ = 9/12.
The answer is D.
