Answer:

33.22 square inches

Step-by-step explanation:

Diameter to Radius: $\frac{1}{2}d = r$

Area of Circle: $\pi r^2$

We are given the diameter of a pancake as 4.6 inches, so the radius is 2.3 inches. Next, we have to apply the area of circle formula with pi as 3.14 and the radius as 2.3

$3.14 * 2.3^2$
$3.14 * 5.29$
$16.6106$

Next, since there's two pancakes, we double 16.6106.

$16.6106 * 2$
$33.2212$

Lastly, we round to the nearest hundredth.

33.2212 ≈ 33.22 square inches

Therefore, the answer is 33.22 square inches.

Find the distance between the two points in simplest radical form. (1, -7) and (7,0)

denis23 [38]

Answer:

The distance between the two given points is equal to √85.

Step-by-step explanation:

Let's recall what the distance formula is:

$\displaystyle \huge\math\boxed{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2} }$

We are defined our two points as:

(x₁, y₁) → (1, -7)
(x₂, y₂) → (7, 0)

We can rewrite this into our different "variables":

x₁ = 1
y₁ = -7
x₂ = 7
y₂ = 0

Now given our distance formula and our variables, we can find the distance between the two points:

$\displaystyle\huge\begin{aligned}d & = \sqrt{(1 - 7)^2 + (7 - 0)^2} \\& = \sqrt{(-6)^2 + (7)^2} \\& = \sqrt{36 + 49} \\& = \math\boxed{\sqrt{85}} \\\end{aligned}$
