Answer:

Step-by-step explanation:

Always use your imaginary scissor:

Cut the above and below circle and the cylinder  role it down-ways like a carpet and you will end up with two circles and a big rectangular.

Surface circle: 7 * 7 * 3,14 = 153.86

Surface carpet: 20 * circle exterior (or the length of the circle)= 20 * 2* 3.14 * 7

Results:

153, 86 * 2 (because we cut 2 circles from the cylinder) + 132,6 = 439.6

Answer: A

Answer:

The manual cost that will take to recreate by the firm is $ 90.51

Step-by-step explanation:

Given:

Number of words the manual contains= 16000

Number of words typed by a clerk in one hour and 20 minutes = 4160

To Find:

The total cost for recreating the manual = ?

Solution:

Step 1:  Finding the Number of hours is need to type 4160 words :

= 1\frac{20}{60} hours

\\\\=1\frac{1}{3} hours

\\\\=\frac{4}{3} hours

So it takes  \frac{4}{3} hours to type 4160 word

Step 2 :  Finding the Number of hours is needed to type 1 word  

= \frac{4160}{\frac{4}{3}}

=4160 \times \frac{3}{4}

= 3120 words per hour

Step 3 :  Finding the Number of hours is needed to type 16000 words

=\frac{\text{ total number of words}} {\text{ number of words written per hour}}

Substituting the values

= \frac{16000}{3120}

=  5.1282 hours

Step 4 :  Finding the cost for recreating the manual.

= number of hours  x cost per hour

=   5.1282 x $17.65

=  90.51
