PLZZ answer!!

Allison has five different sized circular cans. She measures their diameters and calculates their circumferences. Which statement correctly describes what she did for each can?

A) Add 3.14 to the diameter to find the circumference.

B) Divide the diameter by 3.14 to find the circumference.

C) Subtract 3.14 to the diameter to find the circumference.

D) Multiply the diameter by 3.14 to find the circumference.

Answer 1

d

Explanation:

you multiply to find circumference

Answer 2

D) Multiply the diameter by 3.14 to find the circumference.

Explanation:

To find a circumference of a circle

Formular = 2πr

Where

π = 3.14

r = diameter/2

diameter = 2r

d = 2r

Therefore circumference = πd

So the answer is (D) Multiply the diameter by 3.14 to find the circumference.
