This figure is 1/4 of a circle.

drek231 [11]

For this case we have that by definition, the perimeter of a circle is given by:

$C = 2 \pi * r$

Where:

r: It is the radius of the circle.

According to the figure, it is observed that the radius of the circle is 2. Then:

$C = 2 \pi * 2\\C = 2 * 3.14 * 2\\C = 12.56 \ in$

Let's remember that we have a quarter circle:

$C = \frac {12.56} {4}\\C = 3.14$

We round and we have that the correct option is $3.1 \ in$

Answer:

Option A

The attached figure is the image that completes the question

What is the value of the expression i^0 x i^1 x i^2xi^3xi^4

monitta

Answer: The answer is - 1.

Step-by-step explanation: We are given to find the value of the given expression

$E_c=i^0\times i^1\times i^2\times i^3\times i^4.$

We know that 'i' is an imaginary unit and its value is √-1. So, we have

$i^0=(\sqrt{-1})^0=1,\\\\i^1=i=\sqrt{-1},\\\\i^2=(\sqrt{-1})^2=-1,\\\\i^3=i^2.I=(-1)i=-\sqrt{-1},\\\\i^4=(i^2)^2=(-1)^2=1.$

Therefore, the given expression becomes

$E_c\\\\=i^0\times i^1\times i^2\times i^3\times i^4\\\\=1\times \sqrt{-1}\times(-1)\times({-\sqrt{-1}})\times 1\\\\=1\times (-1)\\\\=-1.$ .

Thus, the answer is - 1.
