Question 4 • FL-1205040-M/J Grade 7 Mathematics B -GF

A circle has a diameter of 4 inches. Which statement about the area and circumference of the circle is true?

Answer
A
A comparison of the area and circumference of the circle is not possible because there is not enough information to find both.
B
The numerical values 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 4 inches, so the radius is 2 inches. The circumference is πd = 4π, and the area is πr² = π(2²) = 4π. Their numerical values are equal, so the true statement is “The numerical values of the circumference and area are equal.”
