Surface area = 1808.64in² and volume is 7234.56in³

Step-by-step explanation:

The figure above is a sphere, and it has a diameter of 24in

Radius = ?

Radius = diameter / 2

R = 24 / 2

R = 12in

Surface area of of sphere = 4πr²

Volume of a sphere = 4/3 πr³

π = 3.14

1. Surface area = 4 * 3.14 * 12²

Surface area = 4 * 3.14 * 144

Surface area = 1808.64in²

2. Volume of the sphere = 4/3πr³

Volume = 4/3 * 3.14 * 12³

Volume = 4/3 * 3.14 * 1728

Volume = 7234.56in³

The surface area of the sphere is 1808.64in² and the volume is 7234

Answer:

B) $-\frac{a}{-b}$

Step-by-step explanation:

1. First, we have to know that two negatives equal positive.

2. Given the information above, $-\frac{-a}{b}$ can simplify to $\frac{a}{b}$ .

3. Let's go through each answer choice and see which one also simplifies to $\frac{a}{b}$ .

$\frac{a}{-b}$
$-\frac{a}{b}$

$-\frac{a}{-b}$
$\frac{a}{b}$

Therefore, the answer is B) $-\frac{a}{-b}$ .

In shipment of 850 widgets, 32 are found to be detective. At this rate, how many detective widgets could be expected in 22,000 w

cluponka [151]

Answer:

The number of detective widgets out of 22,000 widgets is 828 widgets

Step-by-step explanation:

Given as :

The total number of widgets = 850

The number of detective widgets out of 850 = 32

Now,

∵ Out of 850 widgets , the number of detective widgets = 32

SO,Out of 1 widgets , the number of detective widgets = $\frac{32}{850}$

∴ Out of 22,000 widgets , the number of detective widgets = $\frac{32}{850}$ × 22,000

Or, Out of 22,000 widgets , the number of detective widgets = 828.23

Hence, The number of detective widgets out of 22,000 widgets is 828 widgets Answer
