Question

A circular traffic island "roundabout" in Road Town has a radius of 12.5 m. If you drove around it twice, what would be the distance you traveled?

Answer 1

Answer:

About 157 meters

Step-by-step explanation:

The circumference of a circle is $2\pi r$. In this case, this means that one loop around the roundabout would be a distance of:

$2\cdot \pi \cdot 12.5\approx 78.5$

Multiplying this by 2, you get a distance of about 157 meters. Hope this helps!

Answer 2

Answer:

157.14 m

Solution,

1 round = circumference

$2\pi \: r$

$= 2 \times \frac{22}{7} \times 12.5$

$= \frac{44}{7} \times 12.5$

Required distance covered:

$2 \times \frac{44}{7} \times 12.5 \\ = \frac{88 \times 12.5}{7} \\ = 157.14 \: m$

hope this helps..

Good luck on your assignment...
