Questions and Answers

What is the relationship between the surface area and volume of a cone?

  • The surface area is half the volume
  • The surface area is proportional to the volume
  • The surface area is unrelated to the volume (correct)
  • The surface area is double the volume
  • In the expansion of $(x + y)^n$, what is the coefficient of the term containing $x^{n-2}y^2$?

  • $\binom{n}{2}$ (correct)
  • $\binom{n}{5}$
  • $\binom{n}{3}$
  • $\binom{n}{4}$
