What is the formula for the circumference of a circle?

Back

The circumference (C) of a circle is given by the formula C = 2πr, where r is the radius.

Front

Back

The value of the expression is 7.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What property is demonstrated by the equation (2 + 9) + 4 = 2 + (9 + 4)?

Back

This demonstrates the associative property of addition.

Front

What is the formula for the area of a circle?

Back

The area (A) of a circle is given by the formula A = πr^2, where r is the radius.

Front

If the area of a circle is 81π square inches, what is the radius?

Back

The radius is 9 inches, since A = πr^2 implies r = √(A/π) = √(81) = 9.

Front

What is the relationship between the radius and circumference of a circle?

Back

The circumference is directly proportional to the radius, given by C = 2πr.

Front

What is the commutative property of addition?

Back

The commutative property states that changing the order of the addends does not change the sum. Example: a + b = b + a.

Front

What is the identity property of addition?

Back

The identity property states that adding zero to any number does not change the number. Example: a + 0 = a.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to distribute multiplication over addition.
