I am trying to write an equation in Excel but I keep getting #NAME? in the cell.
I think it is related to the use of PI but am not sure since the rest is just numbers or cell references.
This is what I wrote in my formula:
= ( 4 * (pi) * A2^2 * 5.671*10^(-8) * (B2)^4 ) 
I applied it to each row and every row gives the same #NAME? output. It's not clear what i am getting wrong. Hope someone can help explain what I am doing wrong.
One thing I notice is it keeps making PI lowercase, why though?

PI is a function and not a variable or cell name so it must be called with ()
=4 * PI() * A2^2 * 5.671*10^(-8) * (B2)^4
