The circumference or perimeter of a circle can be found by multiplying its diameter by 3.14. what is the circumference of a circle that has a diameter of 1/2 inch?

The circumference of the circle with half inch diameter is 1. 57 inch.

Step-by-step explanation:

D = 1/2 inch  =  0.5 inch

Circumference = 3.14  x Diameter

So, now the circumference of the circle  =  d  x 3.14

                                                                   = 0.5 inch x 3.14  

                                                                    = 1.57 inch

Or, C = 1.57 inch

Hence, the circumference of the circle with half inch diameter is 1. 57 inch.

the discriminant is 64 + 4*1*12 = 112

this is prime.
