2. Homework Equations : a=pi x r^2 and (a)(l)= part a

3. The Attempt at a Solution : part a= 0.01356, and I tried plugging it into the equation (1.521x10^-11 m^2)(l)=0.01356

If anyone could find the error in part B!! Please Help

The "(a)(l)= part a" looks wrong. The answer to part a is an area. You cant say "area times length = area".

3. The Attempt at a Solution : part a= 0.01356

That looks right (except you forgot the units).

I don't understand what you did for part (b).

Don't forget that the leaf has two sides, so there are two surface areas. This could be a trick question!what is the area (in m2) of the leaf?

So state your answer as ... m

If you knew the shape, you could also work out the area of its other very narrow side/s.
