Answer 2

Well, first you need to get the area of the Snare and the Bass Drums.

Area for a Circle (which is the shape of both Snare and Bass drums) is:
\[Area (Circle) = pi \times Radius^{2}\]

But you have a diameter for both, and Diameter is is twice the radius, so your Formula will be:
\[Area(Circle) = pi \times (diameter \div 2)^2\]

To solve for the answer, just subtract the area of the Snare to the area of the Bass:
\[Area (Bass) = pi \times (BassDiameter \div 2)^2\]
\[Area (Snare) = pi \times (SnareDiameter \div 2)^2\]

\[Answer = Area(Bass)-Area(Snare)\]

Solve that, and you got yourself an answer.
