Please answer Asap

The five circles making up this archery target have diameters of length $2,4,6,8,$ and $10$. What is the total red area?

Simplify your answer as much as you can. You can use pi in your answer if necessary (for example, if the answer were $3\pi$, you could enter "3pi" or "3*pi" or "$3\pi$").
