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 this equation showing work − 9 ≥− 8(1 + 6v) − 1
Flauer [41]

Answer:

v≥0

Step-by-step explanation:

−9≥−8(1+6v)−1

Step 1: Simplify both sides of the inequality.

−9≥−48v−9

Step 2: Flip the equation.

−48v−9≤−9

Step 3: Add 9 to both sides.

−48v−9+9≤−9+9

−48v≤0

Step 4: Divide both sides by -48.

−48v

−48

In triangle ABC, find B, to the nearest degree, given a = 7, b = 10, and C is a right angle.
padilas [110]

Answer:

55°

Step-by-step explanation:

Since ΔABC is right we can use the tangent ratio to find ∠B

tanB = \frac{opposite}{adjacent} = \frac{10}{7}, hence

B = tan^{-1}(\frac{10}{7}) = 55°
