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

Aleonysh [2.5K]

In this question, it is given that An inverse trigonometric function is used to find the value of an unknown obtuse angle in a triangle. The inverse function returns the angle 68°.

Since the angle is obtuse angle, it means the measurement of the angle is greater then 90 degree. And to find the angle measurement, we have to subtract the given angle from 180 degree.

So the unknown angle is

$180-68=112 degree$

And that's the required answer .
