A cylinder with a radius of 5 feet and height of 2 feet.

What is the surface area of a cylinder with a radius of 5 ft and a height of 2 ft?
60Pi ft2
70Pi ft2
96Pi ft2
150Pi ft2

Answers

Answer 1

Answer:

B, 70pi ft2

Step-by-step explanation:

The equation to find surface area of a cylinder is 2(pi)(r)(h)+2(pi)(r)^2. So now plug the numbers in.. 2(pi)(5)(2)+2(pi)(5)^2 now, simplify. 20pi+50pi= 70pi ft2.

Answer 2

the correct answer is 70Pi ft2

using this formula: A=2πrh+2πr2, substitute r for 5 and h for 2 and put it like this:

a = 2π x 5 x 2 + 2π x 5 squared

2 x 5 x 2 = 20

a = 20π + 2π x 5 squared

5 squared = 25

a = 20π + 2π x 25

multiply 2 by 25 which equals 50

a = 20π + 50π

add 20 and 50 which gives you 70 making the final answer: a = 70π ft 2

Answers

Answer:

Step-by-step explanation:

the rest of the tables have two of the same numbers and it is not a function if it does that.

The answer is B!

In a function, the x input cannot be repeated.

In A, you see that 4 has an arrow pointing to 2 y inputs. That means that 4 is repeated and cannot be a function.

In C, 2 and 5 are both repeated x inputs, so they cannot be functions either.

In D, 0 and -1 both have arrows pointing to 2 y inputs. As stated before, if an arrow points to more than one number, it cannot be a function.

In B, all the arrows point to only ONE y input and none of the x inputs are repeated. Thus, the correct answer is B!

I'd love to help.

An easy method to finding a percentage is converting it into a decimal.

First though, we must simplify 15/20, which would be 3/4, (please let me know if you need the process of simplification)

Then we find the decimal.

We divide the numerator by the denominator.

Answers

Yes

In general, if the dimensions of any two similar shapes are in the ratio m:n , then their areas are in the ratio m2:n2 .

In your case, two similar pizzas (whether circular, rectangular, or what have you) whose dimensions are in the ratio 1:1 have their areas in the ratio 2:1 . Thus, one 12 inch pizza has the same amount of pizza as two 6 inch pizzas.

As you know, the length in cm for each is 4, 6, 4, 3, 5, 6, 5, 4, 3, and 6. So, you must now count how many times 4 is listed, which is 3. Now, you will look at each chart for 3 x's above the number 4. You have now eliminated the middle two. Next, count how many 3's there are, which is 2. Both have those, so eliminating other choices is a no-go. Now, look at how many 5's you have, which is 2. Look at your charts... again, no choice ca be marked-off. Finally, look at how many 6's there are, which is 3. So, look at your last options and find which one has 3 total x's above the 6. And there you go, D.

Step-by-step explanation:

The dimension of interest is the greatest common factor of 12 and 27.

3 · 4 = 12

3 · 9 = 27

The greatest common factor is 3.

Elena needs squares that are 3 inches on each side.

We need to find the common factor of 12 and 27 since they ask to find a square of the same sides. This plays a key part in making sure it fits in the shape correctly with no overlaps and gaps :)

Nitrogen is used by plants for leaf growth and green color. Without nitrogen in the soil, the plant wouldnt grow tall and produce enough food.Phosphorus is used by plants to help form new roots, make seeds, fruit and flowers.This is crucial because crops take up phosphorus only from the soil solution.Potassium helps plants form strong stems and fast growth.
