Answer:
or
Step-by-step explanation:
Given:
A semicircle.
To find:
Arc length of the semicircle = ?
Solution:
Formula for angle subtended by an arc on the center of circle is given as:
where is the arc length and
is the radius of semicircle.
Angle of full circle is
So, angle of semicircle =
Using the formula, we can see that:
So, the answer is:
Arc Length of semicircle = or
The first thing we are going to do for this case is define variables.
We have then:
x: number of days
y: number of pages remaining.
We write the linear equation that models the problem:
The intersection with the vertical axis is:
We evaluate x = 0:
We get the point:
The intersection with the horizontal axis is:
We evaluate y = 0:
We get the point:
