Question

Find the circumference of the circle with the given radius or diameter. (Use 3.14 for pi)

Diameter= 11 cm

Answer 1

The equation for the circumference of a circle is C = 2 π r
the diameter is twice the radius so 11/2 = r
C = 2 π (11/2)
C = 2 (3.14)(5.5)
C = 34.54

Hope this helps ;)

Answer 2

94.985 because I did it in a calculator.
