Question

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

Answer 1

Answer:

r≈2.36cm

Step-by-step explanation:

Answer 2

Answer:

$46.47cm$

Step-by-step explanation:

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

We know that the radius is define as:

$r=\frac{d}{2}= \frac{14.8cm}{2}=7.4cm$

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

$46.47cm$
