Question

According to the image, what is the answer?

Answer 1

Answer:

31.4

Step-by-step explanation:

Write the formula for the circumference of a circle, C=2πr. We know that the diameter of the circle is 10. The radius is half the diameter. So the radius is 5.

Write that into the formula: C=2π(5).

Simplify it by multiplying the numbers together, which are 31.4. That’s the circumference: 31.4
