Answer:

r = 84

Step-by-step explanation:

In order to solve this question, we need the formula for the arc length.

The correct formula is:

$\frac{central-angle}{360} * 2\pi r$

Plugging the numbers into this formula, we find that:

$\frac{120}{360}*2\pi r=56\pi$

$r=84$

How to solve 8x^3+1=0

dem82 [27]

8x^3 + 1 = 0
8x^3 = -1 <----------- Step 1: Subtract 1 from both sides.
x^3 = -1/8 <----------- Step 2: Divide both sides by 8.
x = ∛(-1/8) <----------- Step 3: Cube root both sides
x = -0.5 <----------- This is the final answer when you plug the last step into the calculator
