PT 1
the circumference of a circle is always pi times the diameter. The diameter is 2 times the radius, because diameter is all the way across the circle, whereas radius is from the center of the circle to the edge. Anyways, if the radius is 6, multiply it by 2 and you get 12, so 3.14 times 12 is 37.68, which is the answer.
PT 2
diameter=9 cm. So, just do 9 times 3.14. (diameter times pi = circumference.)
(2*radius times pi = circumference.)
9 times 3.14 is 28.26

(0, -10) is the correct answer,
Applying the law of sines, the measurement indicated are:
7. AB = 24.1 cm
8. BC = 28.0 in.
<h3>What is the Law of Sines?</h3>
Law of sines is: sin A/a = sin B/b = sin C/c.
7. AB (c) = ?
BC (a) = 22 cm
A = 180 - 138 - 22 = 20°
C = 22°
Apply the law of sines:
sin 22/AB = sin 20/22
AB = (sin 22 × 22)/sin 20
AB = 24.1 cm
8. BC (a) = ?
A = 58°
AC (b) = 33 in.
B = 180 - 58 - 33 = 89°
Apply the law of sines:
sin 58/BC = sin 89/33
BC = (sin 58 × 33)/sin 89
BC = 28.0 in.

Answer:
Step-by-step explanation:
For Perimeter, just times both sides by 2 then add those together:
2(5x+2) + 2(3x+8) = 10x +4 +6x +16 = 16x + 20
If they want a solid #:
16x/16 = -20/16
x = -5/4
16(-5/4) + 20
-20 + 20 = 0
However, I think the first answer would the most likely
For Area, multipy the 2 sides using the box method, foil, etc.
I like using the box method (see image)
For the rest, its basically the same thing. The triangle is just adding the sides together
