Answer from: ely093

Arc length = radius * central angle (in radians)
arc length = 63 * 2PI/9 radians
arc length = 14 PI

Answer from: emmapizano

$14\pi\ cm$

Step-by-step explanation:

we know that

The formula to calculate the arc length of the circle is equal to

$arc\ length=r \theta$

where

is the radius

$\theta$ is the central angle in radians

In this problem we have

$r=63\ cm$

$\theta=\frac{2\pi}{9}$

substitute the values

$arc\ length=63(\frac{2\pi}{9})$

$arc\ length=14\pi\ cm$

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.
