Question 8 • FL-1205040-M/J Grade 7 Mathematics B-CR

A circle has a diameter of 6 meters. Which statement about the circumference and area is true?

Answer
A
A comparison of the area and circumference is not possible since the area cannot be determined.
B
The numerical value of the circumference and area are equal.
C
The numerical value of the circumference is greater than the numerical value of the area.
D
The numerical value of the circumference is less than the numerical value of the area.

Explanation

The diameter is 6 meters, so the radius is 3 meters. The circumference is 2π(3) = 6π, while the area is π(3²) = 9π; since 6π is less than 9π, the circumference’s numerical value is less than the area’s numerical value.
