B = L/4πd²

4πd²B = L

(Choice D)

You should be able to multiply both sides of the equation by 4πd² to get L alone. It looks like D, don't know why b is lower case for some answer choices but it should be the same B.

The given equation is:
B=L/4πd^2
Now, you need to get the value of L, this means that you need to get rid of the denominator (4πd^2) while keeping the equation as it is. This means that what you do on one side of the equation needs to be done on the other side as well to keep its value true.

Therefore, you will need to multiply both sides of the equation by 4πd^2.
This gives:
L=B4πd^2

Comparing this value with the choices you have, you will find that the correct choice is D.
