The volume of a cone is given by the formula: V = (1/3)πr²h, where r is the radius of the base and h is the height.

The volume of a cylinder is given by the formula: V = πr²h, where r is the radius of the base and h is the height.

Scientific notation is a way of expressing numbers as a product of a number between 1 and 10 and a power of 10. For example, 1,525,000 can be written as 1.525 x 10^6.

When multiplying powers with the same base, you add the exponents. For example, a^m * a^n = a^(m+n).

When raising a power to another power, you multiply the exponents. For example, (a^m)^n = a^(m*n).

A reflection is a transformation that flips a figure over a line, creating a mirror image.

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

The value of π (pi) is approximately 3.14, and it represents the ratio of the circumference of a circle to its diameter.

To convert a number to scientific notation, move the decimal point to create a number between 1 and 10, and count the number of places moved to determine the exponent of 10.

The area of a circle is given by the formula: A = πr², where r is the radius.
