HELP PLEASE NO LINKS The circumference of a circle is 3.5 centimeters (cm). If the length of the diameter is tripled to make a new circle, which is closest to the circumference of the new
circle?
7.0 cm
14.0 cm
17.5 cm
10.5 cm
The believe the answer is 10.5cm Explanation So first you work out what the original radius would be for the first one (0.55) Then you time it by two to get the diameter (1.1) Since you triple it time the 1.1 by 3 (3.3) Divide 3.3 by 2 (1.66) To find the radios you do ( pie x radius x 2) which finally gets the answer of 10.5
