Which circles have an area of16 pi in2?

Choose all answers that are correct.

A. a circle with a radius of 2 in.

B. a circle with a radius of 4 in.

C. a circle with a diameter of 8 in.

D. a circle with a diameter of 16 in.

The correct answer for the question that is being presented above is this one: "B. a circle with a radius of 4 in." circles have an area of16 pi in2 should have a radius of 4 in.

The area of a circle is this:

Area = pi * r^2

16 pi = pi * r^2

r^2 = 16

r = 4.
