your answer to the nearest
tenth.

Answer 1

B

or

6.3 ft

Explanation:

Answer 2

6.3

Explanation:

Arc length is circumference

C = 2 * pi *r

We are finding a fraction of the total arc length

A circle is 360 degrees

45 degrees / 360 degrees = 1/8

Find the total arc length and multiply by the fraction of the circle

arc length = 2 * pi * r * 1/8

= 2 * 3.14 * 8 * 1/8

=6.28

Rounding to the nearest tenth
