Answer:
13.73 cm 2
Step-by-step explanation:
Area of the whole square 8x8=64
area of 4 quarters of circle = area of 1 circle( with radius 4)
Area circle pi x radius squared
pi x 4squared = pi x 16 = 50.265482.......
Area shaded is the area of the square minus the area of the circle
64-50.265482.... = 13.734517.......
Using proportions, the algebraic expression for the cost of the 24 ads with the discount is:
Cost = 21.12c.
In which c is the cost of a single add.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For this problem, if more than 10 ads are posted, the cost C of each job is discounted by 12%, that is, it is of 88% of C. Hence, the algebraic expression for the cost of the 24 ads with the discount is:
C = 24 x 0.88 x c = 21.12c
In which c is the cost of a single add.
