FAQs

What formulas are provided for 2D shapes like square, triangle, rectangle, and circle?

The sheet lists area and perimeter formulas for common 2D figures, including squares, triangles, rectangles, trapezoids, parallelograms, and circles, such as A = s^2 and C = 2πr (or C = πd).

What 3D surface area and volume formulas are included?

It includes surface area and volume formulas for rectangular/right prisms, cylinders, cones, pyramids, and spheres, such as SA = 2πrh + 2πr^2 for cylinders and V = 4/3 πr^3 for spheres.

Which algebra topics and equation forms are summarized?

The algebra section covers line equation forms and key theorems including slope, slope-intercept, point-slope, standard and quadratic forms, the Pythagorean theorem, simple interest, distance, and mean/median definitions.
