Circumference=2*pi*r or pi*d so if its 16pi you know that your diameter is 16 wich means your radius is 8 because d/2 is your radius. plug the 8 into the area formula wich gives you the formula pi*8^2. 8squared is 64. 64 times pi is 201. <span>or 64pi wich is the area of the same circle with the circumfernce of 16pi

Step-by-step explanation:
There are multiple ways to answer this since you didn't specify the type of measurement to compare it to or any multiple choices so I arranged a list of them.
Considerando las fórmulas para el perímetro y el área de un rectángulo, hay que se chega en una <u>eccuación cuadrática sin solución</u>, o sea, las medidas no son posibles y la persona estaba mintiendo.
<h3>¿Cuál es la fórmula para el perímetro y el área de un rectángulo?</h3>
Considerando que las dimensiones son l y w, hay que:
- El perímetro es: P = 2(l + w).
El <u>perímetro es de 18 m</u>, o sea:
2(l + w) = 18
l + w = 9
l = 9- w.
El <u>área es de 21 m²</u>, o sea:
lw = 21
(9- w)w = 21
-w² + 9 - 21 = 0
w² - 9w + 21 = 0
El discriminante es dado por:
D = 9² - 4 x 1 x 21 = -3.
El discriminante negativo implica que la <u>eccuación cuadrática no tiene solución</u>, o sea, las medidas no son posibles y la persona estaba mintiendo.

The answer is -130. hope this helps.
The given graphs model exponential functions are a, b and c.
Option a, b and c are the correct answers.
To choose the graph.
<h3>What is exponential function?</h3>
A relation of the form y = ax, with the independent variable x ranging over the entire real number line as the exponent of a positive number a.
Given that:
The three graphs in the second picture are the graphs of exponential functions. You can detect it from the L shaped graphs.
The very first graph represents a linear function. A straight line always represents a linear function. In a Linear function, the change in the values of y is constant throughout in relative to change in x values.
Therefore, the given graphs a, b and c are the correct answers.
