Answer:
The perimeter of a semicircle includes the arc and the diameter. Here are some formulas that you can use.
Step-by-step explanation:
P = C / 2 + d
where C is the circumference of the whole circle
P = π r + 2r
where r is the radius
P = (2 + π) r
P = (d π / 2) + d
P = d π / 2 + 2 d / 2
P = (d π + 2 d) / 2
P = (2 + π) d / 2

Answer:
time = 1 hour 24 minutes
Step-by-step explanation:
Given that:
Eastbound train travels at a rate of 65 miles per hour
Westbound train travels at a rate of 85 miles per hour
So speed = 65 + 85 = 150 miles per hour
Total distance = 210 miles
We have to find the time
We know that
Distance = time * speed
OR
time = distance / speed
time = 210/150
time = 1.4 hours
Or it can be written as:
time = 1 hour 24 minutes
