A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for π. (PI)

Answers

                ≈║∧║······→Hello←······║∧║≈

                                           Your answer should be:

                                                             66

                                                          Why...?

                                                         Simple.

       First, you multiply 21 by 22/7. But to make this easier you have to fix in       'improper fraction.' and make it into an improper fraction. Which will become   3 1/7. Now you multiply 21 and 3 1/7. Which will equal 66. So, 66 is your answer.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Let the number be x.

I am thinking of a number. I multiplied this number by 3, subtracted 8, and doubled the result, then added 14.

First part:

2(3x - 8) + 14

6x - 16 + 14

6x - 2

Then I added 50% of what I had and then added 11.

Second part:

(6x - 2) + 50/100 (6x - 2) + 11

6x - 2 + 3x - 1 + 11

9x + 8

Then I divided by 5. After all that, I was left with 8.

Third part:

(9x + 8) / 5 = 8

9x + 8 = 40

Subtract 8 on both sides.

9x = 40 - 8

9x = 32

Divide both sides by 9.

x = 32/9

Thus,

The number that was started with is 32/9.

It takes 4.12 gallons of paint to paint a fence.

How much paint is needed for 1/5 of the fence?

[answer] gallons

Answers

4.12 divided by 5 = 0.824

The amount of paint  needed for 1/5 of the fence is 0.824 gallons.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

Paint= 4.12gallons

Now,

To find the amount of paint needed for 1/5 of the fence, we can use the following proportion:

14.12​=1/5x​

where x is the unknown amount of paint. To solve for x, we can cross-multiply and get:

x=14.12×1/5​

Simplifying, we get:

x=0.824

Therefore, by unitary method the answer will be 0.824 gallons.
