Answer:
Area of a semi circle is 1/2πr²
r = radius
Area = 1/2 × π × 18²
= 162π
= 508.94km²
Hope this helps.

Answer: 131 degrees</h3>
Work Shown:
(angle JIW) + (angle WIH) = angle JIH
(2x+8) + (101) = 11x + 10
2x+109 = 11x+10
2x-11x = 10-109
-9x = -99
x = -99/(-9)
x = 11
So,
- angle JIW = 2x+8 = 2*11+8 = 22+8 = 30 degrees
- angle WIH = 101 degrees
- angle JIH = 11x+10 = 11*11+10 = 121+10 = 131 degrees
The smaller angles add to 30+101 = 131 to confirm we have the correct answer.

Answer:
12/14
Step-by-step explanation:
it says 12 do the high jump and 14 do the long jump so it will be 12/4
