Answer: 39
Step-by-step explanation:
30-8=22
22/2=11
11+2=13
13 times three is (39)
Answer:
The area of the circle is 
Step-by-step explanation:
we know that
The area of a circle is equal to
we have
-----> the radius is half the diameter
substitute the value
The Law of Cosines would be your best bet here, since the unknown side is opposite the known angle 110 degrees.
|AC|^2 = (8 in)^2 + (23 in)^2 - 2(8 in)(23 in)*cos 110 degrees
= 64 in^2 + 529 in^2 - (368 in^2)*(-0.342)
= 593 in^2 + 126 in ^2 approximately
= 719 in^2 approximately
Then the length of side AC is approx. √(716 in^2) = 27 in
