Practical Calculus Flashcards
1
Q
Area of a circle
A
A=pi*r^2
2
Q
Volume of a sphere
A
V=(4/3)pi*r^3
3
Q
Volume of a cone
A
V=(1/3)pi* h * r^2
4
Q
How do you remove variables from shapes that are within other shapes?
A
Slice shape in half to deal with 2d shapes, acknowledge the similar triangles. Build proportions off of that.
5
Q
When in doubt:
A
Decrease the number of variables. It may be possible even if you don’t realize.
6
Q
What does isosceles mean?
A
Having two sides of equal length.
7
Q
Watch out for:
A
Units changing. Make sure you change the units on the spot.
8
Q
Volume of a trapezoidal prism
A
V= (1/2) * (b_1 + b_2) * h * L
9
Q
Area of trapezoid
A
A=0.5(b_1 + b_1) * h
10
Q
What do you always do
A
Draw the situation
11
Q
Surface area of a sphere
A
A = 4pi*r^2
12
Q
When you see angles:
A
Build a trig equation
