Step-by-step explanation:

a) $11 = 3 lines of a classified ad

$x = 2 limes of a classified ad

cross multiply

3x = 22

divide by the coefficient of x

which is 3

3x/3 = 22/3

x = 7.33 approximately 7

x = 7.

b) $11 = 3 lines of a classified ad

$x = 5 lines of a classified ad

cross multiply

3x = 55

diviee by the coefficient of x

which is 3

3x/3 = 55/3

x =18.33 approximately 18

x =18.

The diameter of a sphere is measured to be 4.17 in.
gtnhenbr [62]

Step-by-step explanation:

To find the radius of the sphere we must convert the inches to centimeters

Using the conversation

1 inch = 2.54 cm

If 1 inch = 2.54 cm

4.17 inch = 2.54 × 4.17 = 10.59 cm

<h2>a).</h2>

We can find the radius using the formula

radius =  \frac{diameter}{2}

From the question

diameter = 10.59 cm

So we have

radius =  \frac{10.59}{2}

<h3>radius = 5.30 cm</h3>

<h2>b).</h2>

Surface area of a sphere= 4πr²

where

r is the radius

Surface area = 4(5.30)²π

= 112.36π

= 352.989

We have the answer as

<h3>Surface area = 353 cm²</h3>

<h2>c).</h2>

Volume of a sphere is given by

\frac{4}{3} \pi  {r}^{3}

r = 5.30

The volume of the sphere is

\frac{4}{3} ( {5.30})^{3} \pi

= 623.61451

We have the answer as

<h2>Volume = 623.6 cm³</h2>

Hope this helps you
