The radius of circle S is half the radius of circle L. The radius of circle L is 8 millimeters.

Question

Which measurement is closest to the area of circle S in square millimeters?

Answer 1

The radius of circle S is half of the radius of circle L, so the radius of circle S is 8 mm / 2 = 4 mm.

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

Therefore, the area of circle S is:

A = π(4)^2
A = π(16)
A ≈ 50.27 square millimeters.

The measurement closest to the area of circle S is 50 square millimeters.
