Consider circle o below. the length of arc ba is 8.4 cm and the length of the radius is 8 cm. the measure of angle aoc is 45°. rounded to the nearest whole degree, what is the measure of angle boa? ° rounded to the nearest tenth of a centimeter, what is the length of arc bac?

Rounded to the nearest whole degree, what is the measure of angle BOA?

60

Rounded to the nearest tenth of a centimeter, what is the length of arc BAC?

14.7

Step-by-step explanation:

We have arc length formula as

central angle x perimeter of circle / 360

Hence angle of BOA = central angle of arc BA = 8.4 x 360/2pi (8)

= 60 degrees

II) When angle of AOC = 45 degrees,

arc length = 45/360 (2pi*8) = 6.28

Together arc length BAC = arc BA + Arc AC

=8.4+6.28

= 14.68 cm.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
