@jsobiranski well, i think i was already thinking that a = 1, so we just get 2 in the denom. but yes, i should have been more clear

My teacher prefers the answer to contain pi. How would you do a problem like this and have the answer come out with pi?

when writeing the formula of Sridhar Achariya you hane not written  "a" in the denominator?

[jsobiranski]

You said it correctly, but you forgot to include the "a" in the denominator as part of the quadratic equation.
