It’s 1 km in half hour so she will take 5 hours for 10 km
Answer:
Step-by-step explanation:
By definition, the Arc lenght can be calculated with the following formula:
Where "s" is the Arc lenght, "r" is the radius and is the central angle measured in radians.
From that equation you can solve for dividing both sides of the equation by the radius "r", then:
According to the information given in the exercise:
And you can identify in the figure that the radius of the circle is:
Therefore, you can substitute values into the equation:
Finally, evaluating, you get the following result:
Rounded to the nearest hundredth of a radian:
Answer:

Step-by-step explanation:
Given
Required
The length of PQ
means that the side lengths of LMN are multiplied by 1.25 to get the side lengths of PQR
And it implies that the following sides are corresponding
So, we have:
