It's A.  First of all, one of the only 2 things in math that will NEVER be negative is distances/lengths and times.  You have a distance here, so because one of your 2 numbers is negative, you have to take the absolute value of the difference.  -8-5 = -11, but the absolute value of that is 11.  Put the numbers on a number line and count the units between -8 and +5 and there are 11 units between those 2 numbers.

SA = 2tr2 + 2trh
julsineya [31]

Given:

Radius of the cylinder = 5 in

Height of the cylinder = 30 in.

To find:

The surface area of the cylinder.

Solution:

The surface area of the cylinder is:

SA=2\pi r^2+2\pi rh

Where, r is the radius and h is the height of the cylinder.

Putting r=5,h=30,\pi=3.14 in the above formula, we get

SA=2(3.14)(5)^2+2(3.14)(5)(30)

SA=2(3.14)(25)+942

SA=157+942

SA=1099


Therefore, the surface area of the cylinder is 1099  square inches.

Pls, help with this math question
Aleks04 [339]

Step-by-step explanation:

OCB=CBO(base angle of isosceles triangle are equal)

now,

OCB+CBO+BOC=180°(sum of angles of triangles)

BOC=180-62

BOC=118°

again,

x=BOC/2{inscribed angle is half of central angle standing on Same base}

x=118/2

x=59°

What is 9\3x=5\8 to find the answer i need to ?
tatuchka [14]
9/3x = 5/8 

Using the reciprocal, multiply each side by 3/9. 

5/8 * 3/9 = 15/72
Simplify it : 5/24

x = 5/24

Hope this helps :)

Find the y intercept. I already found the slope is 9.
jeka57 [31]

The slope-intercept form: y = mx + b

We have the slope m = 9, therefore: y = 9x + b.

Next. We have the table:

x | -5 | -2 | 1 | 3 | 4 |

y |-46|-19| 8 |26|35|

(1, 8) → x = 1, y = 8

substitute the values of x and y to the equation:

8 = 9(1) + b

8 = 9 + b |-9

b = -1

Answer: y = 9x - 1 → y-intercept is -1.
