Area of circle formula: πr^2
Since the radius is half of the diameter, divide 38 by two.
r = 19 miles
A = π(19)^2 = π(361)
Now, substitute in 3.14 for π
A = 3.14(361) = 1133.54

Answer: 1133.54 sq. miles</h2>
Answer:
x=36 degrees
Step-by-step explanation:
Remember that all angles of a triangle must add up to 180 degrees due to the Angle Addition Postulate. So let's plug it in! x+65+79=180
Now you solve, x=180-79-65
x=36!
x=36 degrees
If you are trying to ask what the perimeter is for a hexagon that has 3m sides your answer would be 18m
2x - 2y + z = 5....multiply by -1
2x - 2y + 3z = 7
-------------------
-2x + 2y - z = -5 (result of multiplying by -1)
2x - 2y + 3z = 7
-------------------add
2z = 2
z = 2/2 = 1
2x - 2y + z = 5.....multiply by 3
-3x - 3y + 3z = 9...multiply by 2
-------------------
6x - 6y + 3z = 15 (result of multiplying by 3)
-6x - 6y + 6z = 18 (result of multiplying by 2)
-------------------add
-12y + 9z = 33
-12y + 9(1) = 33
-12y + 9 = 33
-12y = 33 - 9
-12y = 24
y = -24/12
y = -2
2x - 2y + z = 5
2x - 2(-2) + 1 = 5
2x + 4 + 1 = 5
2x + 5 = 5
2x = 5 - 5
2x = 0
x = 0
solution is : (0,-2,1)
Answer:
22.95 kg
Step-by-step explanation:
Let's say the farm stand owner starts with x kg of apples.
During the first hour, he sells 15% of the apples:
0.15 x
This means he's left with 85% of the original apples. During the second hour, he sells 20% of the remaining apples:
0.20 (0.85 x)
= 0.17 x
He's sold a total of 15% + 17% = 32% of the apples, so he's left with 68% of the apples. Continuing the pattern, the apples sold during the third hour:
0.25 (0.68 x)
= 0.17 x
He's sold 49% of the apples and is left with 51%. The apples sold during the fourth hour:
0.30 (0.51 x)
= 0.153 x
If 0.17 x = 25.5, then x = 150. So the apples sold during the fourth hour is:
0.153 (150) = 22.95
