8th and 7th Grade Math CAASPP Formulas

These flashcards cover key mathematical concepts and formulas from 7th and 8th grade math, including geometry, algebra, statistics, and functions.

Volume of a Cylinder

V = πr²h

Surface Area of a Sphere

SA = 4πr²

Pythagorean Theorem

a² + b² = c², where c is the hypotenuse.

Distance Formula

d = √((x2 - x1)² + (y2 - y1)²)

Slope Formula

m = (y2 - y1) / (x2 - x1)

Slope-Intercept Form

y = mx + b, where m = slope and b = y-intercept.

Mean (Average)

Mean = Sum of values / Number of values

Mode

The most frequently occurring value.

Probability Formula

P(A) = Number of favorable outcomes / Total possible outcomes

Area of a Rectangle

A = l × w

Volume of a Rectangular Prism

V = l × w × h

Circumference of a Circle

C = 2πr or C = πd

Scientific Notation

ax 10^n, where 1 < a < 10 and n is an integer.

Exponent Power Rule

(a^m)^n = a^(m*n)

Linear Function

f(x) = mx + b
