Answer:
1) 18^2 = 324
324 x 3.14 = 1,017.36 in2
2) half of 25 is:
12.5
12.5^2 = 156.25
156.25 x 3.14 = 490.625 m2
Answer:
5.5
7.5 =
h
23.5
7.5h = 129.25
h = 17.2

The flagpole is 17.2 feet long.
Answer:
8.8
Step-by-step explanation:
Normally, to find the distance between two points, you would use the distance formula, but these two points have the same x-coordinate, meaning they will form a vertical line when connected. To find the length of a vertical line you find the distance between the y-coordinates, in this case -4.7 and 4.1. Finding the distance is the same as finding the absolute value of the difference:
|4.1 -(-4.7)|
|4.1 + 4.7|
|8.8|
8.8
Hey there! :)
Triangles measure 180°
1 side = 100°
180 - 100 = 80
The measure of both unknown angles = 80°
Both are congruent, or the same. That means you have to divide by 2.
80 ÷ 2 = 40
? = 40°
Hope this helps :)
