Acircle has a diameter of 3 meters. which statement about the circumference and area is true?
1)a comparison of the area and circumference is not possible since the area cannot be determined.
2)the numerical value of the circumference and area are equal.
3)the numerical value of the circumference is greater than the numerical value of the area.
4)the numerical value of the circumference is less than the numerical value of the area.

3)The numerical value of the circumference is greater than the numerical value of the area.

Step-by-step explanation:

Given : Diameter of circle 2r = 3 meters

⇒ r = = 1.5 meters

Circumference of circle=

meters

Area of circle=

Clearly the numerical value of the circumference is greater than the numerical value of the area.
