2. If the diameter of a circular wall clock is 30 cm, what is the area of the clock? Note: Since the given is in diameter not radius and radius is half of a diameter, therefore, divide the diameter into 2 to get the radius. Answer: 30 cm / 2=15 cm radius A= π r2 A= 3.14 1 15 c x 1 1 cm A= 3.14 * 225 cm2 A=706.5 cm2

The equation C=2 π r is the formula that relates the circumference of a circle to the radius. This gives us the ability to calculate pi if we physically measure a circle's circumference and radius. Solve the equation for π to get the formula you would use to perform this activity. π = C/2r π =C-2r π =2Cr π = C/2 -r
