Answer:
Step-by-step explanation:
JM is a diameter. 1/2 JM is the radius. 1/2 10 = 5
The radius is 5
The above statement is true if N is the center.
The semi circle has an area of pi r^2/2 = 5^2/2 * pi = 25/2 * pi
12.5 pi
The area of the other part is
(58/360) * pi * r^2 =
0.161 * pi * 5^2
0.161 * pi * 25
4.03 * pi
Now add these two parts together.
12.5pi + 4.03= 16.53 * pi.
That's one possible answer.
Another would be 16.53 * 3.14 = 51.897
If you have choices, list them.

Answer:
x = 1\2 and y = 0
Step-by-step explanation:
8x + 3y = 4 * 5\3
14x - 5y = 7 * 1
40\3x + 5y = 20\3 -------- 1
14x - 5y = 7 ----------------- 2
add equation 1 and 2
82\3x = 41\3
x = <u>4</u><u>1</u><u> </u> <u>3</u>
3 * 82
x = 1\2
subtitute 1\2 for x in equation 2
14\2 - 5y = 7
7 - 5y = 7
5y = 7 - 7
y = 0\5
y = 0
thus x = 1\2 and y = 0
Answer:
The surface area is equal to 
Step-by-step explanation:
The surface area of the triangular pyramid is equal to the area of its four triangular faces
so
In this problem
![SA=4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=SA%3D4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have
substitute the values
![SA=4[\frac{1}{2}(15)(13)]=390\ in^{2}](https://tex.z-dn.net/?f=SA%3D4%5B%5Cfrac%7B1%7D%7B2%7D%2815%29%2813%29%5D%3D390%5C%20in%5E%7B2%7D)
