The equation of circle is (x-a)^{2} +(y-b)^2=r^2 where (a,b) is the center of circle and r is radius of circle. In your question, (a,b)=(0,0) and r=4 so, the equation is x^2+y^2=4^2

Explain how finding 4x384 can help you find 4x5384
yulyashka [42]
Well the 384 part is the harder part because it is a more complex number (for humans) so after you find out what 4x384=(1536) then 4x5000 is simple and you just add the two answers together.

Answer:

One of these numbers is a cube number which means that it could be 1,8, or 27 because those are the first three cube numbers.

If you go with one then you have to find two more numbers that add up to 35 and are a factor of 20, which is not possible.

Then you use 8, which means you have to find two numbers that add up to 26, and are factors of 20, which could be nothing, there aren't any.

Last you do 27 which means you need to find two numbers that add up to 9 and are factors of 27, which can be 4 and 5, because 4+5=9 and 4*5=20.

27,4,5

Hope this helps ;)
