Answer:

Length of arc = 0.628 r

Step-by-step explanation:

Given:

∠ AOB = 36°

Radius = (r)

Find:

Length of arc AB = ?

Computation:

$Length\ of \ arc = \frac{\theta}{360}2\pi r\\\\Length\ of \ arc = \frac{36}{360}(2)(\frac{22}{7} ) (r)\\\\Length\ of \ arc =0.628r$

Length of arc = 0.628 r

The Washington Monument in Washington, D.C., is about 556 ft. tall. A three-dimensional puzzle of the Washington Monument is 24

Umnica [9.8K]

Set up a ratio. But first convert the height of the puzzle to feet so we are comparing the same unit of measure.

STEP 1
convert 24 inches to feet

12 inches= 1 foot

24 inches= 2 feet

STEP 2
set up ratio.

= 2 feet/556 feet or 2:556
simplify both by 2

= 1 ft/278 ft or 1:278

ANSWER: 1/278 or 1:278 (can be written either way)

Hope this helps! :)
