Question

In circle D with m_CDE – 102 and CD = 16 units, find the length of arc CE. Round to the nearest hundredth.

Answer 1

By formula,

$\text{Length of arc=}\frac{\theta}{360}\times2\pi r$$\text{Length of arc CE =}\frac{102}{360}\times2\times\frac{22}{7}\times16=\frac{102\times44\times16}{360\times7}=28.495\approx28.50\text{ units}$
