The base and height of the parallelogram describe the parts of the circle.
Let us consider B as base and H as the height of the parallelogram. Base b is equal to half of the circumference of the circle.
To determine the area of the circle, substitute r for h and πr for b in the area formula by considering r as the radius of the circle.
Therefore, the formula to find the area of a circle is πr² square units.

Answer: Alejandra gave $60 to the cashier.

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given.

We have to subtract to the amount that Alejandra paid(x) the sum of the costs of each product [videogame (24), controller (13) and memory card (169] and the total tax (3). the expression must be equal to the amount received in change.

Mathematically speaking:

x -(24+13+16+3) = 4

Solving for x:

x - 56 =4

x = 4+56

x =60

Alejandra gave $60 to the cashier.
