Answer:
Step-by-step explanation:
area of a full circle is A = πr²
so a quarter of a circle area is A = πr²/4
A = 3.142(7²)/4
A = 38.4895 cm² picture answer
Using π = 3.14 results in
A = 3.14(7²)/4
A = 38.465 cm² written question answer
For comparison purposes,
Carrying the precision of π into many more significant digits results in
A = 38.484510006474...cm²
The average speed will be 140 km per hour.
Distance = 350km
Time = 150 minutes = 150/60 = 2.5 hours.
Average speed = Distance / Time
Average speed = 350/2.5
Average speed = 140 km/hr
