Answer:
861.56 km2
Step-by-step explanation:
the formula for the area of a trapazoid is
a= (a+b/2) + h
Answer is 11
-(-7+4)
Firstly, negative times negative equals to positive so It becomes like this:
+7+4
equals to 7+4
equals to 11!
I hope this is helpful :D
The larger number is
Let larger number be
We have
d=54
22 + 15 = d - 17
37=d-17
54=d
the answer is 4pi or 12.56637061
the arc length equals 2pi x radius ( known angle (120) / 360 which equals 4pi or 12.56637061
