Question

Find the circumference of the portion of a figure.

• A. $180$
• B. $90$
• C. $\pi$
• D. $2\pi$

Answer 1

Answer: (C)

$\pi$

The sector is a part of a circle whose radius is $6$.

Now the angle is given as ${30}^0$.

Hence, the circumference is $=\frac{{30}^0}{{360}^0}\times 2\pi r=\frac{1}{12}\times 2\pi \times \left(6\right)=\pi$
