Answer is C. 12.22cm
C = pi x diameter
Diameter = 20cm
You times pi by 20cm (diameter) to get the circumference of approx 62.84cm
Then times the circumference by the angle in the circle
62.84 x 70/360 = 12.22cm
Answer:
Step-by-step explanation:
Plan 2: x= number of months
y= the cost per call
19x + 0.04y
19(4) + 0.04(20)
76 + 0.8
76.8
So the total will be $76.8
4 cups = 18 g
Divide all by 4 to get 1 cup.
1 cup = 18/4
1 cup = 4.5g
Now, the cosecant of θ is -6, or namely -6/1.
however, the cosecant is really the hypotenuse/opposite, but the hypotenuse is never negative, since is just a distance unit from the center of the circle, so in the fraction -6/1, the negative must be the 1, or 6/-1 then.
we know the cosine is positive, and we know the opposite side is -1, or negative, the only happens in the IV quadrant, so θ is in the IV quadrant, now

recall that

therefore, let's just plug that on the remaining ones,

now, let's rationalize the denominator on tangent and secant,
All possibilities = 9!
possibilities that harry sits at an end = 8! + 8!
possibilities that harry doesn't sit at an end = 9! - 8! -8!
