A disc has a diameter of 23 cm the inner hole in the disc has a radius of 2 cm find the circumference for both the inner hole and the entire disc round to the nearest whole centimeter

The diameter of the entire disc is 72.22 cm, that is, 72 cm rounded to the nearest whole centimeter. In turn, the diameter of the inner circle is 12.56 cm, that is, 13 cm rounded to the nearest whole centimeter.

Step-by-step explanation:

Given that a disc has a diameter of 23 cm and the inner hole in the disc has a radius of 2 cm, to find the circumference for both the inner hole and the entire disc the following calculations must be performed, knowing that the circumference of a Circle is calculated by multiplying 3.14 by the diameter, which in turn measures twice the radius:

23 x 3.14 = X

72.22 = X

Therefore, the diameter of the entire disc is 72.22 cm, that is, 72 cm rounded to the nearest whole centimeter.

3.14 x (2 x 2) = X

3.14 x 4 = X

12.56 = X

In turn, the diameter of the inner circle is 12.56 cm, that is, 13 cm rounded to the nearest whole centimeter.
