Answer:
Step-by-step explanation:
The formula of the circumference of a circle is .
The length of an arch can be found by using the ratio of circumference to the arc.
First, find the circumference of the circle:
Then you find the ratio:
The length of the arc is 90/360, which is 1/4, of the circumference.
Finally, find the length of the arc:

<h3 /><h3>Linear equation</h3>A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and m is the y intercept.
Let y represent the distance in miles and x represent the time in hours. Hence:
Bob speed limit is 66.7 miles per hour
Given a car by y = 70x. The car is driving at 70 miles per hour which is above the speed limit on the highway
