Final answer:

By using the formula C = 2πr and given the circumference of 62.8 inches with π approximated to 3.14, we find that the radius of Janet's circular mirror is 10 inches.

Step-by-step explanation:

The circumference of a circle is related to its radius by the formula C = 2πr, where C is the circumference and r is the radius. Given that the circumference of Janet's circular mirror is 62.8 inches and π is approximated as 3.14, we can find the radius by rearranging the formula to solve for r: r = C / (2π).

Plugging in the values:

  • C = 62.8 inches
  • π = 3.14

We calculate the radius as follows:

r = 62.8 inches / (2 × 3.14)

r = 62.8 inches / 6.28

r = 10 inches

Therefore, the radius of Janet's mirror is 10 inches.
