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

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
