Answer:

The curve surface area(CSA) of a cylinder is 2πrh.

Since diameter=1.5 in.

radius=diameter/2

=1.5/2 in.

=0.75 in.

And, the height of the bottle is 5 in.

Now,

CSA=2πrh

=2π*0.75*5 in^2

=15π/2 or 23.56 in^2

The size of the label needed to cover the entire bottle is 15π/2 or 23.56 in^2.

Answer:

The Surface area of the moon is $4.53 \times 10^{17}$

Step-by-step explanation:

Given:

Diameter of the moon = 3.8 x 10 to the 8th

To Find :

The surface area of the moon = ?

Solution:

The moon is in the shape of of the sphere .

So the surface area of the moon = surface area of the sphere

The surface area of the sphere = $4\pi r^2$

Where r is the radius of the sphere

Radius , r = $\frac{Diameter}{2}$

r = $\frac{3.9 \times 10^8}{2}$

r = $1.9 \times 10^8$

Now the surface area of the moon with radius r = $1.9 \times 10^8$ is

=> $4 \pi \times (1.9 \times 10^8)^2$

=> $4 \times 3.14 \times (1.9 \times 10^8)^2$

=> $12.56 \times 3.61 \times 10^{16}$

=> $45.34 \times 10^{16}$

=> $4.53 \times 10^{17}$

A manufacturer knows that their items have a lengths that are approximately normally distributed, with a mean of 9.8 inches, and

olya-2409 [2.1K]

Answer:

0.6462

Step-by-step explanation:

Given that

Mean (m) = 9.8

Standard deviation (s) = 1.6

Probability that mean length is greater than 9.2

Z = (x - m) / s

Z = (9.2 - 9.8) / 1.6

Z = - 0.6 / 1.6

Zscore = - 0.375 = - 0.375

P(Z >- 0.375) = 1 - P(Z < - 0.375) ;

P(Z < - 0.375) = 0.3538

1 - P(Z < - 0.38) = 1 - 0.3538 = 0.6462

Write the equation in the slope-intercept form. 7x − 4y + 8 = 0

slega [8]

7x - 4y + 8=0 slope intercept is y=mx+b so you have to get y alone
+4y =+4y so add for y on both sides
7x + 8=4y Then divided 4y on both sides
7x/4 8/4= 4y/4
slope intercept form is y=7/4x+2
