An anthropologist visits an igloo with a circular floor. While there, she measures it and calculates that it has a circumference of 18.84 yards. What is the floor's diameter?

The diameter of the floor is 6 yards

Step-by-step explanation:

Here, we are to calculate the diameter of a circular floor that has a circumference of 18.84 yards

Mathematically,

C = π * D

where C is the circumference

Plugging the values of the circumference, we have;

18.84 = 22/7 * D

7 * 18.84 = 22D

D = (7 * 18.84) / 22 = 5.99 which is approximately 6 yards
