Question

An anthropologist visits an igloo with a circular floor. While there, she measures it and calculates that it has a circumference of 48.984 feet. What is the floor's diameter?

)) Use 3.14 for r. If necessary, round your answer to the nearest hundredth.

Answer 1

The formula for circumference of a circle is C = πd, where C is the circumference and d is the diameter.

We are given that the circumference is 48.984 feet, and we can use the approximation of π as 3.14.

Substituting into the formula, we have:

48.984 = 3.14d

To solve for d, we divide both sides by 3.14:

d = 48.984 / 3.14

d ≈ 15.6 feet

Therefore, the floor's diameter is approximately 15.6 feet.
