The circumference of a circle is

Mathematics
1 answer:
Reika [66]2 years ago
6 0

Answer:

1.5 cm

Step-by-step explanation:

1. To find the radius, we use the equation r = \frac{C}{2\pi}

2. Now, we plug in the values and simplify to get the radius. In this case, we'll use pi as 3.14.

  • r = \frac{9.42}{2*3.14}
  • r = \frac{9.42}{6.28}
  • r = 1.5

Therefore, the radius is 1.5 cm.

Solve |3k-2|=2|k+12|
Stella [2.4K]

Answer:

k = 26   or   k = -\dfrac{22}{5}

Step-by-step explanation:

|3k - 2| = 2|k + 12|

\dfrac{|3k - 2|}{|k + 12|} = 2

|\dfrac{3k - 2}{k + 12}| = 2

3k - 2 = 2(k + 12)   or   3k - 2 = -2(k + 12)

3k - 2 = 2k + 24   or   3k - 2 = -2k - 24

k = 26   or   5k = -22

k = 26   or   k = -\dfrac{22}{5}
