A 3 by 4 rectangle is inscribed in circle. What is the circumference of the circle?

1 answer:

8 0

The diameter is the diagonal of the rectangle. Using the pythagorean theorem, you get the diameter being 5. The circumfrance is the diameter*(pi). So the answer is 5(pi). C

Can someone help me

Vikki [24]

Answer:

5x + (x+12) = 90

x = 13

m∡1 = 5(13) = 65°

m∡2 = 13 + 12 = 25°

Step-by-step explanation:

6x + 12 = 90

6x = 78

x = 13

The coordinates of the vertices of a regular polygon are given. Find the area of the polygon to the nearest tenth.

alexandr1967 [171]

Answer:

The area is equal to $8\ units^{2}$

Step-by-step explanation:

we have

A(0, 0), B(2, -2), C(0, -4), D(-2, -2)

Plot the figure

The figure is a square (remember that a regular polygon has equal sides and equal internal angles)

see the attached figure

The area of the square is

$A=AB^{2}$

<u><em>Find the distance AB</em></u>

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$AB=\sqrt{(-2-0)^{2}+(2-0)^{2}}$

$AB=\sqrt{(-2)^{2}+(2)^{2}}$

$AB=\sqrt{8}$

$AB=2\sqrt{2}\ units$

<u><em>Find the area of the square</em></u>

$A=(2\sqrt{2})^{2}$

$A=8\ units^{2}$

Don’t understand can someone help

<h2>Answer: y = -1x + 2</h2>

Step-by-step explanation:

Points ( -3,5 )( 6,-4 )

You use the slope formula to find the slope.

<h3>Note: You'll need to learn the slope formula to make more sense of it, I suggest watching a video about it.</h3>

M = Y2 - Y1 over

X2 - X1

Which is -4 - 5

6 - -3 = -9/9 = -1

The slope is -1

Now to find the y-intercept we use one of the x,y points ( I'll use 6,-4 )

And plug them in

-4 = -1(6) + b

-4 = -6 + b

+6 +6

2 = b

The equation will be y = -1x + 2
