A circle is graphed on a coordinate grid. Its center is at (3, 4), and the circle passes through point (3, 1). What is the approximate area, in square units, of the circle? (Use 3.14 for π.)

Answers

Answer:

it is either 18.84 or 31.40

Step-by-step explanation:

just do it in your head

The area of the circle is 28.26 square units

The center of the circle is given as:

[tex](a,b) = (3,4)[/tex]

The circle passes through the following point

[tex](x,y) = (3,1)[/tex]

Start by calculating the radius using the following distance formula

[tex]r = \sqrt{(x -a)^2 + (y - b)^2}[/tex]

So, we have:

[tex]r = \sqrt{(3 -3)^2 + (4 - 1)^2}[/tex]

[tex]r = \sqrt{9}[/tex]

Square both sides

[tex]r^2 = 9[/tex]

The area of the circle is then calculated as:

[tex]Area = \pi r^2[/tex]

So, we have:

[tex]Area = 3.14 \times 9[/tex]

[tex]Area = 28.26[/tex]

Hence, the area of the circle is 28.26 square units

How do you solve for X?

Answers

Answer:

<L+<M+<N=180

<NLM and <XLN are supplementary meaning their angle measure add to 180.

therefore,44+46+L=180

90+L=180

l=90

If l=90 then the <NLX is also 90 since they are supplementary angles

therefore, 3x+42=90

3x=48

x=16

a college spends 40% of an individual's tuition on salaries and the remainder on other costs if they spend 1,800 on other costs how much is an individual's tuition?​

Answers

Answer:

$3000

Step-by-step explanation:

If the remainder is spent on other costs, then that means 60% of the tuition as spent on other costs.

To find the total tuition, divide 1800 by 0.6:

1800/0.6

= 3000

So, their tuition was $3000

The company plans to have the tanks painted after they are installed. Describe the effect that doubling the diameter has on the amount of paint needed to paint the tanks. What happens when the diameter is increased by a factor of 3?

Answers

Answer:

The effect of doubling the diameter is increased the area to paint as 4 times. So, paint needed is 4 times than it was before. And the area is increased by 9 times when the diameter is increased by a factor of 3. So, paint needed is 9 times than before.

Step-by-step explanation:

Please remember the concept

If side lengths are in the ratio a : b

Then the area are in the ratio of a^2 :b^2

The volume are in the ratio of a^3 :b^3,

When diameter is doubled, the area ratio becomes [tex]x^{2} :(2x)^{2}[/tex] which is simplified to [tex]x^{2} :4x^{2}[/tex]

So, the area is increased by 4 times.

According to this concept , the diameter is increased by the scale factor 3.

Let the diameter of tank is 'x', so the diameter becomes "3x"

So, it's area ratio would be [tex]x^{2} :(3x)^{2}[/tex]

If we simplify it we get [tex]x^{2} :9x^{2}[/tex]

We conclude that  area to be increased by 9 times.

What point is on both lines y=12x+3 and y=x+1

(no graph)

Answers

Step-by-step explanation:

by having two equations that have the same point, you can set the two equations equal to each other

y = 12x + 3, y = x + 1

12x + 3 = x + 1

11x = -2

x = -2/11

when you find the the x value, plug it back into either one of the equations

y = x + 1

y = (-2/11) + 1

y = 11/11 - 2/11

y = 9/11

the point (solution):

(-2/11, 9/11)

Answer:

(-2|11, 9|11)
