Question

What is the approximate circumference of the circle shown below 14.8cm

Answer 1

r≈2.36cm

Explanation:

Answer 2

`46.47cm`

Explanation:

The given circle as a diameter of 14.8 cm, by hypothesis.

We know that the radius is define as:

`r=(d)/(2)= (14.8cm)/(2)=7.4cm`

Then, we use the definition of the length of a circumference, which is:

`L= 2 \pi r`

Replacing all values, we have:

`L= 2 \pi 7.4cm \approx 46.47cm`

Therefore, the circle has an approximate circumference of

`46.47cm`
