Problem page the diameter of a circle measures 28mm . what is the circumference of the circle? use 3.14 for π , and do not round your answer. be sure to include the correct unit in your answer.

Respuesta :

Circumstance of a circle is equal to 2pi*radius.
Diameter is twice as long as radius, so the radius of this circle is 14 mm (half of 28).

2 * 3.14 * 14 = 87.92 mm
