The surface area of the cylinder with the given height and radius is 835.2 square inches

<h3>How to determine the surface area?</h3>

The given parameters are

Height, h = 12 inches; this is represented by the distance between the curved surfaces of the cylinder
Radius, r = 7 inches; this is represented by the distance between the center of the circle to its circumference

The surface area is then calculated using the following formula

A = 2πr² + 2πrh

Substitute the given values in the above equation

So, we have:

A = 2 * 3.14 * 7^2 + 2 * 3.14 * 7 * 12

Evaluate the exponents

A = 2 * 3.14 * 49 + 2 * 3.14 * 7 * 12

Evaluate the products

A = 307.72 + 527.52

Evaluate the sum

A = 835.2

Hence, the surface area of the cylinder with the given height and radius is 835.2 square inches

ya gotta use your eyes and brain huney. it aint that hard. kk? but ill still explain for you.

since x+y=6 and x+y=4. then 4=6. but that is false so no solution.

19. 4x-y+2z =<br> 8x+y-4<br> Find x

Varvara68 [4.7K]

Answer:

x = $\frac{4-2y+2z}{4}$

Step-by-step explanation:

4x-y+2z = 8x+y-4

4x-8x-y+2z = 8x - 8x +y-4

-4x -y +2z= y-4

-4x -y+y +2z = y+y-4

-4x +2z = 2y-4

-4x+2z-2z = 2y-2z-4

-4x = 2y-2z-4

$x= \frac{2y-2z-4}{-4}$ = $\frac{4-2y+2z}{4}$

Suppose that 71% of the surface of the Earth is covered in water, and a random number generator uses latitude and longitude to s

erik [133]

Answer:

.00059 or .0006

Step-by-step explanation:

You are trying to find what won't be in the water because there are many combinations so you use a complement formula.

1-0.79=0.29

Use the left over percentage in an equation to determine the probability.

$1-(0.29)^6=0.000594823$

The exponent 6 comes from the number of locations.
