The area of a circle is 641 m2. What is the diameter?

Answers

Answer 1
The diameter would be d=28.57
Answer 2

Answer:

d = 28.57

Step-by-step explanation:

area = πr^2

so

641 = πr^2

641/π = r^2

204.036637 = r^2

14.2841394 = r

diameter = 2r

14.2841394(2) = d

28.5682788 = d

rounded to nearest hundredth is

d = 28.57

what the answer plss​

Answers

Answer:

To find the circumference, you multiply the radius by 2 and then multiply that by pi (or π). The equation is 2πr

In this case, we already have the radius x 2, which is the diameter. For this circle, the diameter is 12 cm.

The next step is to multiply the diameter, 12 cm, by pi (π is about equal to 3.14)

12 x π ≈ 37.698 cm or 38 cm rounded to the nearest whole number

2) -8(-8x - 6) = -6x – 22

Answers

Answer:

x = -1

Step-by-step explanation:

-8(-8x - 6) = -6x - 22          {Use distributive property}

(-8) * (-8x)  - 6 *(-8) = -6x - 22    

64x +  48 = -6x -22  {Add 6x to both sides}

64x + 6x + 48 = -22         {Subtract 48 from both sides}

         70x     = -22 -48

              70x = -70            {Divide both sides by 70}

                  x = -70/70

x = -1

Renee has 1/4 yard of floral fabric. She cuts it into 5 equal pieces. How long is each new piece of fabric?

Answers

Answer:

[tex]\dfrac{1}{20}\ \text{yards}[/tex]

Step-by-step explanation:

Given that,

Renee has 1/4 yard of floral fabric.

She cuts it into 5 equal pieces.

We need to find the length of each new piece of fabric. It is equal to the total length divided by the total number of pieces. So,

[tex]l=\dfrac{\dfrac{1}{4}}{5}\\\\=\dfrac{1}{4}\times \dfrac{1}{5}\\\\=\dfrac{1}{20}\ \text{yards}[/tex]

So, each new piece pf fabric is [tex]\dfrac{1}{20}\ \text{yards}[/tex].
