Question

An anthropology graduate student measures the floor of a round hut and calculates that it has a circumference of 18.84 yards. What is the floor's radius?

Use 3.14 for ​.

Answer 1

The fllor's radius is 3 yd

Explanation:

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference = 18.84yd

r = radius

π = 3.14

c = 2π * r

we replace with the known values

18.84yd = 2 * 3.14 * r

18.84yd = 6.28 * r

18.84yd / 6.28 = r

3yd = r

The fllor's radius is 3 yd
