Use 3.14 for Pi. If necessary, round your answer to the nearest hundredth

Answer 1

radius=6.8mm

Explanation:

Circumference is the distance round a figure.

let C denotes circumference=42.704milimeters

Formula for calculating C=πD ;where

is the diameter.

42.704mm=3.14×D

D=42.704/3.14

=13.6mm

R=13.6/2

=6.8mm
