Essential SAT Math Formulas for Effective DSAT Preparation
When it comes to SAT preparation, mastering math concepts is key to achieving a high score. Fortunately, the SAT provides a formula reference sheet to support students during the test. Knowing these formulas beforehand will save valuable time and reduce exam stress. Below, we explore all the math formulas provided on the digital SAT reference sheet and highlight the most important ones for your SAT preparation journey.
Math Formulas For DSAT Preparation
1. Circumference and Area of a Circle in SAT Preparation
For effective SAT preparation, remember the circle formulas as naturally as you recall your home address.
- Area = πr²
- Circumference = 2πr
Many students mix the two up, so be mindful while practicing during your SAT preparation.
2. Area of a Rectangle for SAT Preparation
This formula is intuitive and frequently tested. For your SAT preparation, always recall:
- Area = length × width (for a square, both sides are equal).
Though perimeter is not included on the SAT formula sheet, you can calculate it as: (length + width) × 2.
3. Area of a Triangle – A Must for SAT Preparation
One of the most used formulas in SAT preparation is the triangle area:
- Area = ½ × base × height
Since time is limited on the test, ensure you know this formula cold rather than relying on flipping back to the reference sheet.
4. Volume of a Box in SAT Preparation
Students often spend too much time here. Remember during SAT preparation:
- Volume of a rectangular box = length × width × height
- Volume of a cube = s³
- Surface area of a cube = 6s²
Surface area of a box isn’t provided on the SAT sheet, but knowing it can be useful in practice questions.
5. Cylinder Formula in SAT Preparation
You may not frequently see cylinder problems, but the formula is available. During SAT preparation, familiarize yourself with it so you don’t waste time memorizing unnecessarily—it’s right there on the reference sheet.
6. Pythagorean Theorem – Core of SAT Preparation
This is one of the most essential formulas to know cold in SAT preparation. It helps you quickly find missing sides in right triangles:
- a² + b² = c²
Practice fluency with this theorem so you can apply it without hesitation.
7) 30:60:90 Triangle in SAT Preparation
This special triangle appears occasionally. While it isn’t necessary to memorize it fully for SAT preparation, knowing how to use the reference sheet quickly will save time. Make sure you understand the relationship between the sides.
8) 45:45:90 Triangle – A Key Shortcut in SAT Preparation
For better efficiency in SAT preparation, you should practice the 45:45:90 triangle.
- The two equal sides have the same length.
- The hypotenuse is always √2 times longer than each equal side.
Even if you don’t memorize it, knowing how to read the SAT reference sheet correctly is crucial during your practice.
