Never. If you set up an equation making them equal to each other and you solve it, it will give you that they are equal. Even when you divide them separately (3 by 6 and 2 by 4 ) you get 1/2 for both. You can't change that. Look in the picture
D. Polar zones
Due to the tilt of the earth, the very top, known as the polar zones, has an extreme amount of day/night time, depending on the position the Earth currently is around the sun.
(21/7) = 3
(6)^2 = 36
3+3(36) = 111

We are asked to calculate the circumference of the two circles; all the required information is given to us.
![\triangle~\fbox{\bf{KEY:}}](https://tex.z-dn.net/?f=%5Ctriangle~%5Cfbox%7B%5Cbf%7BKEY%3A%7D%7D)
- The formula for the circumference is:
.
'
In this formula,
![\star~\mathrm{C=Circumference; \\ \pi =pi,\;which\;is\;3.14; d=diameter}}](https://tex.z-dn.net/?f=%5Cstar~%5Cmathrm%7BC%3DCircumference%3B%20%5C%5C%20%5Cpi%20%3Dpi%2C%5C%3Bwhich%5C%3Bis%5C%3B3.14%3B%20d%3Ddiameter%7D%7D)
------------------------------------------
Question #1
------------------------------------------
<u>Circumference of Circle</u>
<u></u>
<h3>Given value(s):</h3>
So to solve for circumference, we should substitute 10 for y, which gives us:
![\mathrm{C=10\pi}](https://tex.z-dn.net/?f=%5Cmathrm%7BC%3D10%5Cpi%7D)
Circumference:
![\bigstar~\mathrm{\underline{C=31.4\:cm}}](https://tex.z-dn.net/?f=%5Cbigstar~%5Cmathrm%7B%5Cunderline%7BC%3D31.4%5C%3Acm%7D%7D)
------------------------------------
Question #2
-------------------------------------
This time, the diameter is 6 units. We follow the same steps to find the circumference:
![\mathrm{C=6\pi }](https://tex.z-dn.net/?f=%5Cmathrm%7BC%3D6%5Cpi%20%7D)
Upon multiplication,
![\bigstar~\mathrm{\underline{C=18.8\:cm}}](https://tex.z-dn.net/?f=%5Cbigstar~%5Cmathrm%7B%5Cunderline%7BC%3D18.8%5C%3Acm%7D%7D)
Hope it helps you out! :)

Answer:
obtuse, straight
Step-by-step explanation:
If you insist on two answers, there is only one pair of answers that are self-consistent:
obtuse, straight
__
m∠A = (11(13) +37)° = (143 +37)° = 180° . . . . a straight angle, also obtuse
