Question

A circle has a diameter of 32 m. What is its circumference?

Use 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

100.48 m

Explanation:

C=2(3.14)r

C=2(3.14)(16)

C= 100.48 m

Answer 2

`C=32(3.14)=100.48\text{ meters}`

Explanation:

We know that the circle has a diameter of 32 meters.

And we want to find its circumference.

The circumference of a circle is given by the formula:

`C=\pi d`

Where d is the diameter.

So, we will substitute 32 for d and we will use 3.14 for π. Hence, our circumference will be:

`C=32(3.14)=100.48\text{ meters}`
