Answer 1

Answer:

12.56 units

Step-by-step explanation:

Hello!

The circumference of a circle given the diameter is $C = d\pi$, where d is the diameter.

Given that π is 3.14, solve for the circumference.

Solve for C

• $C = d\pi$
• $C = 4(3.14)$
• $C = 12.56$

The circumference is 12.56 units.
