What is the approximate circumference of a circle with a diameter of 400 inches? A. 628 inches B. 1256 inches C. 1884 inches D. 2512 inches I'm thinking 1256 because 400 x 3.14 = 1256. Am I correct?

OpenStudy (prominer10000):

Yeah I used that and got 1256. Do you think I'm correct? @rebeccaxhawaii

we are finding circumference so 2 x 3.14 x the radius - remember the radius is half the diameter
