suppose the radius of a circle is 2. What is the circumference Either enter an exact answer in terms of use 3.14 for pie and enter your answer as a decimal. I NEED HELP ASAP!!!??

Respuesta :

12.56

To find the circumference of a circle, the formula is diameter • π. The diameter is twice the radius, so first you must multiply 2 • 2 = 4. So the diameter is 4.

The question states to use 3.14 instead of π, so from here we multiply 4, the diameter, by 3.14 to find the circumference.

4 • 3.14 = 12.56, so the circumference is 12.56
12.56. You find the circumference by doing pi times the diameter. The radius is half the diameter. In other words, you do 3.14 times 4. Please mark brainliest if this is right.
