@princeevee are you here ?
princeevee:
?
jhonyy9:
i like help you
jhonyy9:
any idea ?
jhonyy9:
than the diameter = 8000 miles how many miles will be the radian ?
jhonyy9:
i not can giving to you the right answer so please collaborate and i will help you getting it easy - ok ?
princeevee:
i know, my internet is faulty today, sorry.
jhonyy9:
the diameter of a circle = how many radius ? sorry above i ve wrote radiani - so this mean radius
jhonyy9:
|dw:1530564837651:dw|
princeevee:
4000?
jhonyy9:
yeh - what is this ?
jhonyy9:
4000 miles is what ?
jhonyy9:
is the length of ... ?
jhonyy9:
courage please i m here to help you ,to correct your answer
jhonyy9:
D = 2r 8000 = 2r so r= ?
princeevee:
16000?
jhonyy9:
no you ve wrote above right - but you need to know what is this 4000
jhonyy9:
than D = 2r and we know that 8000 = 2r => r = ?
jhonyy9:
8000 = 2r divide both sides by 2 and will get r = ?
princeevee:
4000, yeah,
princeevee:
2000 if you divide that
jhonyy9:
no - this 4000 is right - so this is the length of a radius
jhonyy9:
so than you see this posted image how many is the distance from the Moon to Earth ?
princeevee:
239,000
jhonyy9:
ok.
jhonyy9:
|dw:1530566174112:dw|
jhonyy9:
do you can calcule from this the length of x ?
princeevee:
about 250k?
jhonyy9:
please make the calcule exactly - bc. there you know exactly distance and there is a right triangle where you need using Pythagora's theorem and will get easy the length of x ok. ? @ThisGirlPretty
jhonyy9:
@princeevee how you get the x using pythagora's ?
princeevee:
trying to
jhonyy9:
how is the pythagora's formula ?
jhonyy9:
|dw:1530566920882:dw| yes ?
jhonyy9:
how many will be the length of hypothenuse in case of your above exercise ?
jhonyy9:
@ThisGirlPretty do you know it ? please
jhonyy9:
why is so difficily ? this is easy just see the posted image please
jhonyy9:
the length of hypothenuse will get assuming the length of radius with the distance from the Moon to Earth yes ?
princeevee:
yeah?
jhonyy9:
so now can you calcule the x exactly easy - yes ?
jhonyy9:
hypothenuse = 4000 + 239000 = ?
