A = 28.26 units^2
Step-by-step explanation:
The formula for the area of a circle is:

We can just plug in the numbers and solve.


28.26 units^2
Complementary angles add up to 90°.
You are given one angle that is 63.6°.
Let's make the other angle "x".
63.6 + x = 90
To find x, all you have to do is subtract the other angle (63.6) from 90.
90 - 63.6 = 26.4
x = 26.4
The measure of the complementary angle is 26.4°.
Answer:
Prob = 0.514
A. independent
Step-by-step explanation:
The probability that the club chooses a girl and then a boy for the representative spots
Total = 15
Boys = 6
Girls = 9
Prob of 2 person, a girl and a boy
=( 9C1*6C1)/(15C2)
= (9*6)/(105)
= 54/105
= 0.514
