Area
| Find the area of a: | using the equation: | |
| Circle | a =  r2 |
 |
| Parallelogram | a = bh |  |
| Rectangle | a = lw |  |
| Trapezoid | a = 0.5h(b1 + b2) |  |
| Triangle | a = 0.5bh |  |
Perimeter
| Find the perimeter of a: | using the equation: | |
| Circle (The perimeter of a circle is called Circumference) |
c = 2r c = *d |
|
| Parallelogram | p = 2a + 2b | |
| Rectangle | p = 2l + 2w | |
| Trapezoid | |
|
| Triangle | p = a + b + c | |
Volume
| Find the volume of a: | using the equation: | |
| Sphere | v = 1.33**r3 |
 |
| Right Circular Cylinder | v = r2h |
 |
| Right Circular Cone | v = .33**r2h |
 |
| Form of equation: | Formula: | ||
| Standard Form | ax + by = c | ||
| Slope Intercept Form/ Y Intercept Form | y = mx + b | m = slope b = y intercept | |
| X Intercept Form | x = (y - b)/m | b = y intercept m = slope | |
| Point-Slope Form | y - y1 = m(x - x1) | (x1,y1) m = slope | |
