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.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
