according to the royal canadian mint act a 50 cent canadian coin must have a diameter od 27.13 milimeters. To the nearest hundreth what is the circomference in milimeters
C = π*d = π*27.13 ≈ 85.23141
85.23141 rounded to the nearest hundredth = 85.23 or 85.23mm
i am confused
To find the circumference of a circle, you can use the formula:
C = πd, where C represents the circumference and d represents the diameter.
Using the given diameter of 27.13 millimeters, we can calculate the circumference.
Plugging in the values, we have:
C = π × 27.13
To calculate the circumference to the nearest hundredth, we can use the value of π rounded to two decimal places, which is approximately 3.14.
C ≈ 3.14 × 27.13
Simplifying this equation, we have:
C ≈ 85.2322
Rounded to the nearest hundredth, the circumference of a 50 cent Canadian coin would be approximately 85.23 millimeters.
