What is the formula for finding the perimeter of a circle?

Back

The perimeter of a circle, also known as the circumference, is calculated using the formula C = 2πr, where r is the radius.

Front

What is the relationship between radius and diameter?

Back

The radius is half of the diameter. Formula: r = d/2.

Front

What does the distributive property state?

Back

The distributive property states that a(b + c) = ab + ac, meaning you can distribute a number across a sum.

Front

How do you combine like terms in an expression?

Back

To combine like terms, add or subtract the coefficients of terms that have the same variable.

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using the formula P = 2(l + w), where l is the length and w is the width.

Front

What is the formula for the area of a circle?

Back

The area of a circle is calculated using the formula A = πr², where r is the radius.

Front

What is a simplified expression?

Back

A simplified expression is an expression that has been reduced to its simplest form, with no like terms or parentheses.

Front

What is the purpose of using a graphing tool like DESMOS?

Back

DESMOS is used to visualize mathematical functions and verify calculations, especially for complex expressions.

Front

What is the width of a frame if it is stated to be 4 inches wide on each side?

Back

If the frame is 4 inches wide on each side, the total width added to the dimensions of the object is 8 inches (4 inches on each side).

Front

What is the difference between perimeter and area?

Back

Perimeter is the total distance around a shape, while area is the amount of space inside a shape.
