The radius of a circle of diameter $24 \mathrm{cm}$ is  $\mathrm{cm}$.

Match the following

Find the central angle of the shaded sectors (each circle is divided into equal sectors).

For the sector with given measures, find the length of the arc, area and perimeter. $(\pi =3.14)$

central angle $45°, r=16 \mathrm{cm}$

For the sector with given measures, find the length of the arc, area and perimeter. $(\pi =3.14)$ central angle $120°, d=12.6 \mathrm{cm}$

From the measures given below, if the area of the sector is $k {\mathrm{m}}^2$, find the value of $k$.

From the measures given below, the area of the sector is $\mathrm{k} {\mathrm{cm}}^2$. Find the value of $\mathrm{k}$.

If the central angle of the sector whose measures are given below is $k°$ then find the value of $k$.

Use $\left(\pi =\frac{22}{7}\right)$
