The radius of the circle is 7 inches what is the approximate length of AB (AB is 135 degrees

1 answer:

6 0

We know that
circumference=2*pi*r
for r=7 in
circumference=2*pi*7------> 14*pi in

if 360° (full circle) has a length of------------ 14*pi in
135°-----------------------------> x
x=135*14*pi/360----------> x=5.25*pi in--------> 16.49 in

the answer is
5.25*pi in or 16.49 in

A store pays $22 for a duffel bag. The store marks up the price by

fredd [130]

Marks UP the price by 30%.

There's two ways:
30% of $22, plus $22.
OR
130% of $22.

To save time, 130% of 22.

130/100 x 22
= 13/10 x 22
=13/5 x 11
=143/5
= 28.6

$28.6

Hope this helps!

He coordinates of the vertices of a polygon are (−2, −2) , (−2, 3) , (2, 4) , (3, 1) , and (0, −2) .

Answer: The perimeter is 17.52

Step-by-step explanation:

1. You can plot the points, as you can see in the graph attached.

2. As you can see in the graph, the points are:

$A(-2,-2)\\B(-2,3)\\C(2,4)\\D(3,1)\\E(0,-2)$

And the lenghts AB and EA are:

$AB=5$

$EA=2$

3. To find the other lenghts, you can apply the formula for calculate the distance between two points:

$distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

4. Thefore, you have:

$BC=\sqrt{(2-(-2))^{2}+(4-3)^{2}}=4.12\\CD=\sqrt{(2-3)^{2}+(4-1)^{2}}=3.16\\DE=\sqrt{(3-0)^{2}+(1-(-2))^{2}}=4.24$

5. The perimeter is:

$P=AB+CD+DE+EA\\P=5+4.12+3.16+4.24+2\\P=17.52$

Which statement is true about the circumference of a circle? The circumference is equal to the radius of the circle. The circumf

Irina18 [472]

<h3>The true statement about circumference of a circle is: circumference is found by multiplying Pi by the diameter</h3>

Solution:

The circumference of a circle is given as:

$\text{circumference } = 2 \pi r$

Where,

"r" is the radius of circle

We know that,

$diameter = 2 \times radius\\\\d = 2 \times r\\\\d = 2r$

Thus the circumference can also written as:

$\text{circumference } = 2 \pi r\\\\\text{circumference } = \pi \times d$

Thus, the circumference is found by multiplying Pi by the diameter is correct statement

A pair of supplementary angles have measures of x° and (x + 8)°. What is the value of x? Please show work, Thanks!

neonofarm [45]

If you have supplementary angles, that means that the angles have to add up to 180°. So x+(x+8)=180° So I would combine like terms 2x+8=180 Now subtract by 8 on both sides which gives me 2x=172 now divide by 2 and x equals 86°! I hoped this helped you!
