Answer:
See explanation
Step-by-step explanation:
Assuming you are talking about a square of side length
Then we can find the area of the square using
where s is the side length of the square.
We substitute the value to get:
Write exponent as multiplication
Multiply to get:
Therefore the area is 1/25 cm²
Answer:
The arc length of the semicircle is half the circumference of the full circle
Answer: b)
Step-by-step explanation:
Given,
speed of train A travelling east = 55 mph
speed of train B travelling west = 70 mph
time train A travelled while train B was at rest = 45 min or
so, Distance travelled by train A while train B was at rest =
=
Now, after 'T' hour both the train will travel;
train A = 55T
train B = 70T
hence, the distance (D) between two train in miles will be;
⇒ D = 41.25 + 55T + 70T
⇒ D = 125T + 41.25
