Answer:
(26,-2)
Step-by-step explanation:
For any two points on coordinate plane (x1,y1) and ( x2,y2)
coordinate of midpoint is given by (x1+x2)/2 , (y1+y2)/2
Given
(x1,y1) = (-4,-8)
midpoint : (11,-5)
let other point be x2 and y2
therefor by using formula for midpoint coordinate given above we have
midpoint : (11,-5) = (-4+x2)/2 , (-8+y2)/2
Hence point
11 will be equivalent to (-4+x2)/2
11 = (-4+x2)/2
=> 11*2 = -4+x2
=>22 + 4 = x2
=>x2 = 26
similarly
-5 will be equal to (-8+y2)/2
-5 = (-8+y2)/2
=> -5*2 = -8+y2
=> -10 + 8 = y2
=> y2 = -2
Therefore coordinates of other point is (26,-2).
2×2=4 ( for one face)
so there r 6 faces = 6×4=24 square inches

Answer:
7 km
Step-by-step explanation:
Substitute:
The equation for area of a semi-circle is 
A = 
76.97 = 
Multiply by 2 on both sides:
2(76.97) = (
)2
153.94 = 
Divide by pi on both sides:
153.94 = 
/pi /pi
49.03 ≈ 
Find the square root:

7 = r
