$\frac{1170pi}{360m}$ km

Step-by-step explanation:

To find the length of the minor arc, you find the circumference of the circle multiplied by the arc angle, which is $\frac{45}{m}$ over 360 degrees.

Circumference of the circle with center B = 13×2×pi

= 26pi

Length of minor arc = 26pi × $\frac{45}{m}$ × $\frac{1}{360}$

= $\frac{1170pi}{360m}$ km

$6\frac{4}{7}$

Step-by-step explanation:

$5\frac{2}{7}+1\frac{2}{7}$

Add the whole numbers 5 and 1

5+1=6

Add the fractions (Don't forget you only add the numerators, not the denominators. You leave the denominators the same.)

$\frac{2}{7}+\frac{2}{7}=\frac{4}{7}$

Combine the answers

$6+\frac{4}{7}\\\\=6\frac{4}{7}$

$5\frac{2}{7}+1\frac{2}{7}$ as a mixed number in the simplest form is $6\frac{4}{7}$
