Answer:
15 hours.
Step-by-step explanation:
20 can be divided into quarters, 3 quarters is 15/20 hours.
Let length, width, and height be s.
Then diagonal of any face would be √( s² + s² ) = √( 2s² )
And we know that it measures √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.
Now we have to solve √( 500 ) = √( 2s² )
Square both sides:
500 = 2s²
Divide both sides by 2:
250 = s²
Take the square root of both sides:
√(250) = s ≈ 15.8113883
Rounding to nearest tenth:
s ≈ 15.8
Final answer: 15.8
Hope this helps.
Maybe A I’m not one hundred percent sure but good luck
I believe It is A. infinitely solutions
Answer:
113.04 cm
Step-by-step explanation:
We know the formula to find the area of a circle is
And we are told to use 3.14 instead of pi so what we have now is,
We are also told the radius, r, is 6. So our equation now looks like this,
is the same as 36, because 6x6 is 36.
Now we have,
Which equals 113.04 and that is the area!
Hope that helps and have a great day!
