1. The circumference if a circle can be found by multiplying pi (n = 3.14) by the diameter of the circle.

2. If a circle has a diameter of 4, it’s circumference is 3.14*4 = 12.56.

3. If you know the radius, the diameter is twice as large.

−3x + y = 4,<br><br> −9x + 5y = −1<br> find x and y

katrin [286]

Answer:

9x - 3y = -12

-9x +5y = -1

2y = -13

y = -13/2

-3x - 13/2 = 8/2

-3x = 21/2

-6x = 21

x = -21/6 = -7/2

(-7/2, -13/2)

Find c.

Alexxx [7]

9514 1404 393

Answer:

14.9 cm

Step-by-step explanation:

To find c using the Law of Sines, you must know angle C. That is found from ...

C = 180° -A -B = 180° -150° -12° = 18°

Then the law of sines tells you ...

c/sin(C) = b/sin(B)

c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)

c ≈ 14.9 cm
