Question 2 What is the LATERAL SURFACE AREA of this cylinder?

Mathematics
1 answer:
erastova [34]2 years ago
7 0

The lateral surface area is the area of the side thing, not the 2 circles.

If we imagine to stretch the side out, we can get a rectangle with base the circumference to the base circle, and height of 9 inches.

Therefore this area is pi*8*9=72π

Evaluate each expression using the values m = 7, r = 8, and t = 2.
user100 [1]

So I'll walk through the first 2. Then please try the other ones and let me know if you run into more problems.

5m-6

If m is equal to 7, then replace m with 7.

5(7)-6

5x7=35 so the expression is now 35-6. Solve.

35-6=29

So that was the first one.

4m+t

We just do what we do with the first problem.

4(7)+(2)

4x7=28 so the expression is 28+2.

28+2=28

---

hope it helps

p.s. When there is subtraction, add. When there is division, multiply to cancel that out. When there is multiplication, divide to cancel. etc.

James spent $20.16 on comic books. Each comic book cost $0.72. After he read the comic books, James sold each one for $0.20 less
adell [148]

Answer:

$14.56

Step-by-step explanation:

<u><em>Steps to answering this question </em></u>

  1. Determine the total number of comics bought. This can be done by dividing the total amount spent on comics by the unit price of a comic
  2. Determine the selling price of the comic
  3. multiply the amount of comics bought by the selling price

the total number of comics bought = total amount spent on comics / per unit price of comics

$20.16 / $0.72 = 28

selling price = 0.72 - $0.20 = $0.52

Total amount received = selling price x total comics bought

$0.52 x 28 = $14.56

Which products result in a difference of squares? Check all that apply. (5z + 3)(–5z – 3) (w – 2.5)(w + 2.5) (8g + 1)(8g + 1) (–
Helen [10]

Answer:

Option 2  (w-2.5)(w+2.5)=w^2-2.5^2\\ and option 4 (-4v-9)(-4v+9)=-(4v+9)(-)(4v-9)=4v^2-9^2

Explanation:

In option 1 (5z+3)(-5z-3)=-(5z+3)(5z+3)=-(5z+3)^2  which is not the difference of squares

In option 2 (w-2.5)(w+2.5)=w^2-2.5^2\\ using the formula

(a+b)(a-b)=a^2-b^2\\Here \\a=w,b=2.5

Clearly, the difference of squares

In option 3(8g+1)(8g+1)=(8g+1)^2 not the difference of squares

In option 4(-4v-9)(-4v+9)=-(4v+9)(-)(4v-9)=4v^2-9^2

Clearly the difference of squares

In option 5 (6y+7)(7y-6)=42y^2+13y-42 not the difference of squares

In option 6 (p-5)(p-5)=(p-5)^2 not the difference of squares

Justin walk 5 kilometer and he turn right and he swim 35 meters why the apple is red?​
Morgarella [4.7K]

Answer:

Red apples get their color from anthocyanins. These are pigments, or natural colorings, that develop as the apple grows. It absorbs all the colors of the rainbow—except for red. The red light reflects off the apple and our brain and eyes work together to let us know what color we are seeing

Step-by-step explanation:

The first part of the question does not correlate to the final question the problem is asking. Therefore, we just need to find out why apples are red. A simple google search can tell you why ^^
