Answer:

S=1444.4

Step-by-step explanation:

they already gave the formula so

13 is the height, 10 is the radius

plug it in to the formula (using 3.14 for pi)

S=2(3.14)(10)^2+2(3.14)(10)(13)

S=628+816.4

S=1444.4

Answer:

1444.4 ft.

Step-by-step explanation:

Using the formula, 2πr² + 2πrh, we can plug-in the unknown values.

'π' means pi; 'r' means radius; 'h' means height.

The radius is 10; the height is 13.

3.14 is used for pi.

(2π10²) + (2π10 · 13) = 1444.4.

Therefore, the surface area of this cylinder is 1444.4 ft.

What are the x- and y- intercepts of the graph of 9x-3y = 18?
sineoko [7]

Step-by-step explanation:

9x - 3y = 18

Solve for y:

1. 3y= 9x + 18

2. y= 3x + 6 (This is the equation you will graph)  

To graph:  

Make a table for y = 3x +6.

If x =0, y=6

If x =1, y=9

If x =-1, y=3

You could get as many points as you like, however you need at least TWO, to be able to draw the line.

Alecsey [184]

Answer:

"differential selection"

Step-by-step explanation:

If your friend took the test twice and passed both times with a score above 90% then the minor difference in price is most likely due to "differential selection". The first test had  questions that he had a little more experience in solving, while the second time he was most likely given a couple questions that he wasn't as prepared for as he was the first time. This is most likely the cause for the difference in percentiles.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
