The diameter of a pizza is 14 inches. The pizza has 8 slices of equal size. Which of the following is the closest to the area of
qwelly [4]

Answer:

Step-by-step explanation:

First let us find the area of the whole pizza. Area of a circle is:

A=\pi r^2

Then, we have diameter as:

diameter\div2=radius

So, then using these formulas we would have,

16\div2=8\\A=8\pi \text{ or }25.12

Now, one slice is \frac{1}{8} of the entire pizza. So, we would have:

8\pi\div8=1\pi\\\text{ or }\\25.12\div8=3.14

Find the distance between the points <br> (-8,-6) and (4, 10)
never [62]

Answer:

d=20

Step-by-step explanation:

To find the distance between 2 points we use the distance formula

d = √(x2 - x1)²+(y2 - y1)²

The given points are (x1= -8, y1 = -6) and (x2 = 4, y2 = 10).

Substitute the given points into the distance formula.

d = √(4 + 8)²+(10 +6)²

d = √144+252

d= √400

d = 20
