Yes, it would be B.

C= π x r
radius would be 28/2 = 14
2π x 14 = 87.92 millimeters

To find the circumference of a circle, you can use the formula:

Circumference = π * diameter

Given that the diameter of the sphere is 28 millimeters, we can substitute this value into the formula:

Circumference = π * 28

To find the value of π (pi), we use an approximation of 3.14. Substituting this value, we can calculate the circumference:

Circumference = 3.14 * 28

Calculating this multiplication, we get:

Circumference ≈ 87.92 millimeters

Therefore, the correct answer is B. 87.92 millimeters.
