Answer:

108 in

Step-by-step explanation:

The figures are similar, so if we find a relation of the area and the diagonal in rectangle 1  we can apply it to rectangle 2.

rectangle 1 :

72/x=12

x=6

therefore

72/6=12

rectangle 2:

A/x=18

A/6=18

6*18=108

A=108 in

Hope this helps

Find the lateral area of a cylinder with the given measurements. Use 3.14 for pi and round your answer to the nearest tenth.

height: 15 centimeters

radius: 9 centimeters

Question 11 options:

787.3 cm2

1356.5 cm2

847.8 cm2

889.9 cm2

So we know the formula for the lateral area of a cylinder is:

AL=2πrh

now all we have to do is put the given value in place of the correct variable then solve like so:

AL=2*3.14*9*15

AL= 847.8 cm2

so the answer is the third option

hope this helps

Find the simple interest paid to the nearest cent for each principal, interest rate, and time.
igor_vitrenko [27]

<u>Answer:</u>

The simple interest for $152, 2.5%, 18 month is $5.7

<u>Solution:</u>

Given that, principal amount = $ 152, interest rate = 2.5 % and time period = 18 months.

Now we have to calculate the simple interest for above given values.

We know that, simple interest is given as

=\frac{\text { principal amount } \times \text { interest rate } \times \text { time period in years }}{100}

By substituting the given values, we get

\text { Simple interest }=\frac{152 \times 2.5 \times 18 \mathrm{months}}{100}

By converting 18 months to years we get,

\begin{array}{l}{=\frac{152 \times 2.5 \times \frac{18}{12}}{100}} \\\\ {=\frac{152 \times 2.5 \times \frac{3}{2}}{100}} \\\\ {=\frac{152 \times \frac{3}{2}}{40}} \\\\ {=\frac{76 \times 3}{40}=\frac{19 \times 3}{10}} \\\\ {=\frac{57}{10}=5.7}\end{array}

Hence, the simple interest is $5.7
