Answer:
radius of circle = 3cm
circumference = 18.84cm
diameter = 6cm
Step-by-step explanation:
if the diameter of circle is 6cm
radius of circle = diameter/2
= 6/2
= 3
circumference of circle = 2r
= 2 x 3.14 x 3
= 6.28 x 3
= 18.84
<h2><em><u>Mark me as braniest</u></em></h2>Answer: proportion
Two polygons are similar if and only if there is a proportion that maps a preimage to its image.
