The area of circle can be found using the formula πr² and since we know that semi circle is half the circle so its formula will be 1/2πr².
First we will find the radius.
20/2 = 10
Radius is 10.
A = 1/2(3.14)(10)²
A = 157
Hope this helps :)

Answer: The jet's speed from A to B would be 5.5 km/hr.
Step-by-step explanation:
Since we have given that
Distance = 2500 meter
Outbound speed be x
Average speed be
Time = 9 hours 10 minutes =
According to question, it becomes,
Hence, the jet's speed from A to B would be 5.5 km/hr.
