Junior High School Mathematics Formulas
The following are some math formulas that are commonly taught at the junior high school level:
1. Area of the Square: L = s x s
2. Circumference of the Square: K = 4 x s
3. Area of the Triangle: L = 0.5 x a x h
4. Perimeter of Triangle: K = a + b + c
5. Area of Circle: L = π x r x r
6. Circumference of the Circle: K = 2 x π x r
7. Volume of the Cube: V = s x s x s
8. Block Volume: V = p x l x t
9. Cylinder Volume: V = π x r x r x t
10. Pythagorean theorem: a² + b² = c²
11. Straight Line Equation Formula: y = mx + c
12. Quadratic Equation: ax² + bx + c = 0
13. Distance, Speed and Time Formulas: v = s/t, s = v x t, t = s/v
14. Equation of a Circle: (x-a)² + (y-b)² = r²
Note: In addition to formulas, make sure you understand the basic concepts involved and practice continuously to master math well.
