Answer:
x = (+ - ) 9
Step-by-step explanation:
x^2 = 81
u know how u can sometimes cancel something out by doing the opposite.
This is one of those times as well. the opposite of ^2 = square root.
so if we take the square root of both sides, this will cancel out the^2 on the left side.
sqrt (x^2) = sqrt(81)
x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.
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!
