What is the area of a circle with a diameter of 16?

ExtremeBDS [4]

The formula to find the area of a circle is:

$a= \pi r^{2}$

Step 1:
We will be dividing the diameter by two to find the radius.

16 ÷ 2 = 8

Step 2:
We will find what 8 squared is.

$8^{2}$

8*8= 64

Step 3:
We will be inputting this number is our formula.

$A= \pi 64$

Step 4:
We still need to multiply $64 * \pi$ to find our area.

$64 * \pi$ = 201.0619298297467673

Step 5:

We will round this to the nearest whole number.

Our rounded number is 201

Our answer:

$\boxed{a=201}$ or $\boxed{a=201.06}$

The table below shows values for functions f(x) = g(x) <br> What are the solutions to f(x) = g(x)?

MakcuM [25]

The solutions to f(x) = g(x) are where the x-values for which the output f(x) is equal to the output of g(x).

What I mean by this is for instance, you input 7 into f(x) and g(x) and you get the same answer, then 7 is a solution.

Here, we are looking in columns two and three to see which rows are equal. It looks like when you input 0 into both f(x) and g(x), you get 2, and when you input 1 into both f(x) and g(x), you get 3. Therefore, (0,2) and (1,3) are your solutions.
