how do i find the diameter of a circle with only knowing the area?

Answers

Answer 1

Answer:

2 * (Area/pi)^(1/2) = diameter

Step-by-step explanation:

The equation for the area of a circle is A = pi * r^2

We can divide both sides by pi to get:

A/pi = r^2

Then take the square root of both sides to get:

(A/pi)^(1/2) = r

Then, since D = 2 * r, we can multiply both sides of the above equation by 2 to get:

2 * (A/pi)^(1/2) = 2 * r = D

Answer 2

Answer:

d=2[tex]\sqrt{a/\pi }[/tex]

Step-by-step explanation:

Find the height of the trapezoid

Answers

Write A=h(b1+b2)/2, where A represents the trapezoid's area, b1 represents one of the base lengths, b2 represents the other base length and h represents the height. Rearrange the equation to get h alone. Multiply both sides of the equation by 2 to get. 2A=h(b1+b2).

The volume of this figure is approximately 418.88 centimeters squared!

Step-by-step explanation:

The volume for a right circular cone is V = (π)(r^2)(h/3)

Substituting known values is as follows:

V = (π)(r^2)(h/3)

V = (π)(4^2)(25/3)

V = (π)(16)(25/3)

V ≈ 418.88 cm^3

Find the missing term(s) of the geometric sequence: 39, a2 , 975, ... Hint: r can be positive or negative.

Answers

9514 1404 393

Answer:

  ±195

Step-by-step explanation:

For some common ratio r, your missing term satisfies ...

  39r = a2

  a2·r = 975

So, ...

  975 = 39r^2

  25 = r^2

  r = ±√25 = ±5

The missing term a2 = 39r could be either of 195 or -195.

Matt is ordering basketball jerseys For his country's league. Last year he ordered 512 jerseys. 64 those jerseys were orange. If he ordered 600 jerseys this year, how many of them will be Orange if the ratio of orange jerseys to all the jerseys remain the same? Round to the nearest whole number.

Answers

Answer:

75

Step-by-step explanation:

Step 1

Matt is ordering basketball jerseys For his country's league. Last year he ordered 512 jerseys. 64 those jerseys were orange.

The ratio of all Jerseys to Jerseys that are Orange =

512 : 64

8 : 1

Step 2

If he ordered 600 jerseys this year, how many of them will be Orange if the ratio of orange jerseys to all the jerseys remain the same?

Since we are maintaining the ratio in step 1

Let the number of orange jerseys = x

600 : x = 8 : 1

Hence

600/x = 8/1

Cross Multiply

8 × x = 600 × 1

8x = 600

x = 600/8

x = 75

Therefore, this year, the number of orange jerseys = 75

Answers

Answer:

4090 ml - 4.9L

1.4km - 4901m

Step-by-step explanation:

A liter is made up of 1000 ml so 4.9 l is equvilant to 4,900 ml.

A kilometre same as litre is made up of a 1000 m. So 1.4 km is 1400m

However, ml and l is a measurement of volume while m and km is a measurement of distance.

What is the Slope-Intercept Form of 16x + 4y = 44

Answers

Answer:

Y=-4x+11

Step-by-step explanation:

So first you gotta realize that slope intercept from is

y=mx+b

So you have the equation of

16x+4y=44 as the initial response

Now you just have to isolate it into the from of y=mx+b

SO first subtract 16x on both sides to isolate the 4y since its the initial response as y=mx+b

Then when that is done you should have the answer of

4y= 44-16x

Now You have to isolate the “y”.

By dividing 4 on both sides to get the new equation which will be

y= 11-4x

You can leave it like that or just move around the (x) to make it more plausible as the answer of y=mx+b

y= -4x+11

However you would put it,  that is the answer

y= -4x+11

And

y= 11-4x

Answers

Since both equations equal y they need to equal each other.

2x - 5 = -3x + 10

Add 3x to both sides:

5x -5 = 10

Add 5 to both sides

5x = 15

Divide both sides by 5

X = 3

Now solve for y by replacing x with 3:

Y = 2(3)-5 = 6-5 = 1

Y = -3(3)+ 10 = -9+ 10 = 1

Check: replace y with 1 and solve for x:

1 = 2x -5

Add 5 to both sides

6 = 2x

Divide both sides by 2

X = 3 ( True)
