Answer:

arc = 5π units

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here we have a semicircle with d = 10, so r = 5, then

arc = $\frac{1}{2}$ × 2π × 5 = 5π units

WILL GIVE BRAINLIEST TO 1ST 4x+188=6x+216

Ulleksa [173]

Answer:

x = -14

Step-by-step explanation:

Let's solve your equation step-by-step.

4x + 188 = 6x +216

Subtract 6x from both sides:

4x + 188 - 6x = 6x + 216 - 6x

-2x + 188 = 216

Subtract 188 from both sides:

-2x + 188 - 188 = 216 - 188

-2x = 28

Divide both sides by two:

$\frac{-2x}{-2}=\frac{28}{-2}$

$x = -14$
