To solve for n, we need to isolate it on one side of the equation.
Start by multiplying both sides of the equation by 7 to get rid of the fraction:
7B = pi*x^2*n
Next, divide both sides of the equation by pi*x^2 to isolate n:
7B / (pi*x^2) = n
So, the solution for n is:
n = 7B / (pi*x^2)
Solve for n.
B=(1)/(7)pix^2n
