Answer:
628.4 cm²
Step-by-step explanation:
Area of semicircle : (πr^2)/2
(3.152*(20^2)) / 2
(3.142 *400) /2
1256.8 / 2
628.4
The temperature at 5 am was -3 degrees
12-15=-3
The difference in distance between Aero plane A and B is; 34.67 km
<h3>How to calculate bearing?</h3>
To get the bearing;
∠H = (115 - 90) + (270 - 203)
∠H = 92°
Then, we will use cosine rule to get the distance between both Planes A and B.
d_ab = √(18² + 29² - 2(18 * 29) * cos 92)
d_ab = √(324 + 841 + 36.435)
d_ab = 34.67 km

Answer:
A x=1/4
Step-by-step explanation:
2/3x = 1/6
Divide by 2/3
so 1/6 ÷ 2/3
= 1/6 • 3/2
= 3/12
= 1/4
