66 in.
why
The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle.
In this case, the radius is 10.5 inches.
C = 2 * π * 10.5
C ≈ 2 * 3.14 * 10.5
C ≈ 66 inches
Therefore, the closest measurement to the circumference of the clock in inches is 66 inches.
In this case, the radius is 10.5 inches.
C = 2 * π * 10.5
C ≈ 2 * 3.14 * 10.5
C ≈ 66 inches
Therefore, the closest measurement to the circumference of the clock in inches is 66 inches.
