You can solve this problem and calculate the arc lenght, by applying the following formula:
s=θr
s: it is the arc lenght.
θ: it is the central angle (θ=2π/3).
r: it is the radius of the circle (r=10 inches).
When you substitute these values into the formula, you obtain the arc lenght (s):
s=θr
s=(2π/3)(10)
Then, you have that the value of the arc lenght is:
s=20.94 inches
Answer:
£21
Step-by-step explanation:
Cost of 18 drinks = £54
Cost of 1 drink
= Cost of 18 drinks/18
= £54/18
= £3
Cost of 7 drinks
= Cost of 1 drink × 7
= £3 × 7
= £21
It should be noted that a polygon is a flat two dimensional closed shape that has straight sides.
<h3>What is a polygon?</h3>
Your information is incomplete. Therefore, an overview of a polygon will be given.
A polygon simply means a plane figure which is described by a finite number of straight line segments that are connected in order to form a closed polygonal chain.
In this case, the length of a line segment can be measured by simply measuring the distance between the two endpoints.
It's simply the path between two points that has a definite length that can be measured.
Examples of polygon include triangles, quadrilateral, pentagon, etc.

Answer:
See below
Step-by-step explanation:
The total cost depends on:
1. Software cost
2. each yearbook cost
<u>Variables:</u>
Let the total cost be (y) and the cost of each yearbook be (x).
To print x yearbooks, it's going to cost 15x
Also, there is software (fixed cost) cost of 800
So total cost would be:
y = 800 + 15x
