Question

The circumference of a circle is 8π units. If the radius of the circle is doubled, what is the new circumference?

Answer 1

16π

Step-by-step explanation: To find the diameter, we multiply whatever the radius is by 2.

So, 8 is our radius. If we double it, we multiply it by 2. Let's solve.

8 × 2 = 16

So, 16π is the answer.

Answer 2

The new circumference would be 16π
