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

Write the standard form of the equation of the circle with its center at (-5,0) and a radius of 8 what is the equation of the ci
Leto [7]

Answer:

\large\boxed{(x+5)^2+y^2=64}

Step-by-step explanation:

The standard form of an equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the center (-5, 0) and the radius r = 8. Substitute:

(x-(-5))^2+(y-0)^2=8^2\\\\(x+5)^2+y^2=64

Which expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign? (5 points) A square
andrezito [222]
The correct answer is d) 4x² - 4x + 1.

The area of a square is found by squaring the side length:

(2x-1)² = (2x-1)(2x-1) = 2x*2x - 2x*1 - 2x*1 - 1(-1) = 4x² - 2x - 2x + 1 = 4x²-4x+1
