At Mario's Pizza, a large pizza has a diameter of 18 inches. What is the area of two pizzas?

irinina [24]

First, the area of the pizza then double it.

Area for a circle: Area = $\pi$ * r^2

Plug in the values.

We will use 3.14 for $\pi$ .

We need the radius. So half the diameter to get the radius.

18 / 2 = 9

Area = 3.14 * 9^2
Area = 3.14 * 81
Area = 254.34

Then multiply 2 to get the double the area.

254.34 * 2 = 508.68

So, the answer to this question is D. 508.68 in. 2.

A light bulb filament is one-hundredth of an inch thick, with an allowable error of 2 percent. What is the least allowable thick

Andreyy89

Answer:

0.00998 Inches

Step-by-step explanation:

Thickness of the light bulb filament = 0.01 Inch

Allowable error = 2%.

2% of 0.01 = 0.02 X 0.01 =0.0002 Inch

Therefore, the allowable thickness of the bulb filament

$=0.01 \pm 0.0002 $ Inches$

We can then calculate the least allowable thickness of the filament as:

$=0.01 - 0.0002 \\=0.00998$ Inches$

The least allowable thickness of the filament is 0.00998 Inches.
