Question

ABC is a central angke in a cirvle with center B. The length of the radius is 13 km and m

Answer 1

`(1170pi)/(360m)`km

Explanation:

To find the length of the minor arc, you find the circumference of the circle multiplied by the arc angle, which is
`(45)/(m)` over 360 degrees.

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

= 26pi

Length of minor arc = 26pi ×
`(45)/(m)` ×
`(1)/(360)`

=
`(1170pi)/(360m)`km
