Test Strategy

The best strategy for a beginner would be to focus on problems 1- 25. That's more than 1 minute per question. Although speed is a necessity, accuracy has more of an effect on your score. Whenever you practice, work on reducing the time you take on each number cruncher. KNOW YOUR CALCULATOR. I, Kevin, know just about every function on my HP and I'm trying to learn all of them for my N-spire. I am also trying to be able to finish all the number crunchers (35 in all) in under 10 minutes. It's been a while, but it would leave me at least 20 minutes to solve the stated and geometry problems.

Geometry

Frustum
R1=radius of lower base
R2=radius of upper base
s=slant height
h=altitude(height in center)
O=semicone angle(angle the cone makes at the top from the middle of the circle)
S=lateral surface area
T=total surface area
V= Volume

s=SQRT((R1-R2)^2 +h^2)=h/(cosO)=(R1-R2)/(sinO)
S=pi(R1+R2)s
T=pi[R1^2+R2^2+(R1+R2)s]
V=1/3*pi*h(R1^2+R2^2+R1*R2)
