What symbol do you use for square root on pc?
2 answers:
For this case we must find the values of "a" and "b" that make the expressions equivalent:
We have:
We take common factor "2" from the numerator and denominator:
Eliminating common factors of numerator and denominator:
So, we have that the values of a and b are:
Answer:
Note: To write square root on pc we use sqrt

To solve this, we are going to use the surface are of a sphere formula: 
where
is the surface area of the sphere
is the radius of the sphere
We know for our problem that
and 
, so lets replace those vales in our formula:
Now, we just need to solve our equation for:
or
Since the radius of a sphere cannot be a negative number,.
We can conclude that the radius of a sphere with surface area <span>2,122.64 </span>
is 13 in.
