Step-by-step explanation:
3.14×13.5
In the case of a circle, the formula for area, A, is A = pi * r^2, where r is the circle's radius. Since we know that a semicircle is half of a circle, we can simply divide that equation by two to calculate the area of a semicircle. So, the formula for the area of a semicircle is A = pi * r^2/2
The distance between them is 75 miles
after 1 hour the train will go 125 miles
125 miles.....1 hour
75 miles..........x hour
x=75/125=75/125*60=36 minutes
d is the answer
well 7-6 is one then you'll find common demonstrators with the fractions then simplify them then subtract them to get 1 1/4
2x3:7 = 0,857
You and your friend have 0,857 chance to be choosen.
