Answer:

6280 mm squared

Step-by-step explanation:

To find the area Of a cylender we multiply pi times r squared times the height, and we can put pi as 3.14

the radius is 10 mm, and the height is 20 mm.

pug it in.

3.14 times 10 squared times 20.

3.14 time 100 time 20

314 times 20

6280 mm squared

Answer: 6300

Step-by-step explanation:

Volume of cylinder=V=πr^2h

As given:

Radius=r=10mm

Height=h=20mm

Substituting values in above formula

V=(3.14)(10)^2(20)

V=6283.18531

After Round off 6300

Without using technology, describe the end behavior of f(x) = 3x32 + 8x2 − 22x + 43. (2 points)

Elis [28]

Answer:

This function is an even-degree polynomial, so the ends go off in the same directions, just like every quadratic I've ever graphed. Since the leading coefficient of this even-degree polynomial is positive, the ends came in and left out the top of the picture, just like every positive quadratic you've ever graphed. All even-degree polynomials behave, on their ends, like quadratics.

Subtract. –5.8 – (–8.4) A. –14.2 B. –2.6 C. 2.6 D. 14.2

svp [43]

-5.8 - (-8.4)

When we multiply two negatives they become a positive. In this situation, where there is no other number, you can assume there's basically a 1 in that place.

-5.8 - 1(-8.4) would be just as correct. (If this helps visually clarify anything.)

So we take that -1 and multiply it by that -8.4. Multiplying 1 against anything leaves it the same, so we just need to change the sign. Two negatives make a positive.

-5.8 + 8.4

Now we add these together.

This gives us our final answer of 2.6

What is the median of this set of data: 593, 588, 540, 434, 420, 398, 390, 375

Aleks04 [339]

Answer:

426

Explanation:

To find the median number in a set of data start by reordering the data from least to greatest.

original data set:

593, 588, 540, 434, 420, 398, 390, 375

data set from least to greatest:

375, 390, 398, 420, 434, 540, 588, 593

Next, you would usually just have to find the middle number in the data set and that would be your median. However, this data set has no one number that is directly in the middle. So, we will add both middle numbers together and then divide our answer by two.

375, 390, 398, 420, 434, 540, 588, 593

420 + 434 = 854

854 ÷ 2 = 426

Therefore, the median of the given data set is 426.
